Marco Beretta	f0f5bdd3a0	fix: persist failed summaries and stop double-rendering memory mutations ... Stamp the failed marker on the aggregated summary part server-side, mirroring how ON_RUN_STEP_CLOSED already stamps runStepStatus. The SDK aggregator ignores a complete event that carries no summary, so an errored round's partial deltas were saved unmarked and a reload re-rendered the truncated text under "Conversation summarized". Skip memory attachments that carry a toolCallId in the message-level MemoryArtifacts decoration. Those calls already render inline as a MemoryCall card with the same key, value and outcome, so one mutation appeared twice. Attachments with no originating call keep the decoration as their only surface. Keep a reasoning-bearing group expanded when Open Thinking Dropdowns by Default is on. The folded-in THINK part only renders inside the group body, which is not even mounted while collapsed, so the preference had no visible effect until the action group was opened by hand. Give same-named place results unique keys. Several branches of one chain share a name and often carry no identifier, so rows whose address, rating and map target all differ collided on one React key.	2026-09-06 18:46:10 +02:00

Danny Avila	5e3cdd0b2c	📮 fix: Consume an Invite Only Once the Account Exists (#15611) ... * 📮 fix: Consume an Invite Only Once the Account Exists `checkInviteUser` deleted the invite token and then called `next()`, but everything that can still reject a registration runs after it: the schema, the allowed-domain check, and the email-already-in-use check. A mistyped password confirmation therefore destroyed the invite — the invitee corrected it, resubmitted, and got "Invalid invite token" with no way back short of an admin re-inviting them. The deletion moves to `registrationController`, after `registerUser` reports success. That report needed a new signal. `registerUser` returns the same 200 and the same generic message whether it created an account or found the email already in use — deliberately, so the response cannot be used to enumerate accounts — so the status alone cannot say whether an account exists. It now also returns `userCreated` on the creation path, which the controller reads and never forwards; the response body is unchanged. A failed deletion is logged rather than surfaced. By that point the account exists, and leaving a usable invite behind is recoverable in a way that telling the user their registration failed is not. Fixes #15541 * ♻️ test: Fold the Invite Tests Into the Existing AuthController Spec From Copilot's review. The new spec reached for `jest.requireActual` on `@librechat/data-schemas`, `~/server/services/AuthService` and `~/models`, which pulls real implementations into a unit test — `~/models` builds the data-schemas methods against mongoose — and diverges from `AuthController.spec.js`, which stubs each module outright. Rather than restate that harness with narrower stubs, the tests move into the spec that already has it. `deleteTokens` joins its `~/models` mock, which also keeps that shared mock in step with the controller's imports: a stale mock there hands the controller an undefined function, and the omission only surfaces when some later test happens to exercise the path.	2026-09-04 15:38:32 -04:00
Danny Avila	fe30e3db32	🪫 fix: Back Off Failed Retention Deletes (#15608) ... * 🧹 fix: Stop Undeletable Files Starving the Retention Sweep `getExpiredFiles` returns the oldest `expiredAt` first, capped at `limit`, and `processDeleteRequest` leaves the record in place when storage deletion fails. Nothing records the failure, so the same files come back at the head of the next batch an hour later, forever: no backoff, no cap, and — once `limit` of them cannot be deleted — no file that expires afterwards is ever swept again. On the deployment behind #15511 that is ~29k stranded objects permanently occupying a 100-slot queue, which is why fixing the Code Interpreter side alone (LibreChat-AI/code-interpreter#85) would not have resumed deletion there. Failures are now recorded on the file. `deletionRetryAt` holds it back with a backoff doubling from one sweep interval to a day, and `deletionAttempts` retires it from the query entirely once it reaches `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` (10, so roughly five days of retries). Both fields are absent on existing records and absence means "never attempted", so nothing already in the collection changes eligibility. The record itself is kept rather than deleted — the reference is what an operator needs to reconcile a bucket the sweep could not clear, and dropping it would restore the silence that made this leak invisible. Raising `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` re-admits everything previously given up on, which is the supported way to resume once the storage-side failure is fixed; the give-up is logged with that instruction. The counter is incremented server-side with `$inc` so concurrent sweeps on separate nodes cannot overwrite each other's progress toward the cap, and a failure to record a failure is logged and skipped rather than aborting the rest of the batch. * 🧭 fix: Delete Code Environment Files Through the Route That Exists `deleteCodeEnvFile` tried `/sessions/:sid/objects/:fid` before falling back to `/files/:sid/:fid`. Both have been there since #13424, but only the second is mounted by any released codeapi — the first gained DELETE in LibreChat-AI/code-interpreter#85 — so every deletion paid a guaranteed 404 and a wasted round trip, and #15511 read that 404 as the whole bug. Call `/files/:sid/:fid` directly. It is the safe direction to collapse toward: codeapi has mounted it since its first release, so this works against older deployments as well as post-#85 ones, whereas keeping the other path would not. Collapsing the loop tightens two behaviours that only existed to serve it. A 405 now surfaces instead of being swallowed on the way to a second attempt; there is no second route to try, and a service that refuses the method should say so. A 404 is still treated as "already gone" — that is the only thing it can now mean — but it is logged rather than passed over in silence, because a 404 caused by a misconfigured base URL looks identical and this branch drops the file's metadata record either way. * 🔒 fix: Settle sweep retry state from the write, not the read Two findings from the review of 0e52924. - `recordFailure` derived the attempt number by adding one to the count the batch had queried. Two nodes sweeping the same file read the same value, so both believed themselves to be the same attempt: each `$inc` landed, the stored count crossed `FILE_RETENTION_SWEEP_MAX_ATTEMPTS`, and neither caller ever saw the threshold. The file drops out of the query — the starvation guard still holds — but the give-up is never reported, and that log line is the operator's only notice, and carries the instruction for resuming. Return the count from the increment itself so every caller gets a distinct attempt number and exactly one observes the cap. The same staleness shortened the backoff, so `deferExpiredFile` now writes with `$max`: a deferral can only move later, and a node that computed a shorter delay cannot pull the file forward past one another node already committed. - The backoff doubled from a hard-coded hour while claiming to start from one sweep interval. At the default they coincide; away from it the schedule stops meaning anything — on a six-hour sweep the first three attempts all land on consecutive passes, and on a five-minute one the first retry skips twelve. Derive the base from `FILE_RETENTION_SWEEP_INTERVAL_MS`, floored at a minute so a pathologically short interval cannot spend the whole give-up budget on a transient outage. * 🧯 fix: Keep the give-up notice and the retry budget honest Four findings from the review of ee1bac5. - The give-up was reported after the deferral write, inside the same catch. Once the increment lands the counter is durable, so `getExpiredFiles` already excludes the file; a deferral that then failed left only the generic recording error and dropped the one line naming the file and saying how to resume. Report it as soon as the increment returns, and let the deferral fail on its own. - Retry deadlines were measured from `Date.now()` after the deletion I/O, but `startExpiredFileSweep` arms its interval before the sweep runs. A one-interval delay therefore expired just *after* the next scheduled pass, which skipped the file and pushed its first retry out by a whole extra interval — and the same drift applied to every delay that is an exact multiple. Anchor deadlines to the sweep's start instead. - The threshold used `>=`, so once two nodes pushed a file past the cap every one of them past it logged the give-up: one error per replica per exhausted file rather than one actionable notice. Only the attempt that lands exactly on the cap reports it. - Retry state outlived the content it described. `processCodeOutput` reuses a record for a repeated `(filename, conversationId)` — new bytes, new storage key, and a fresh `expiredAt` from `getRetentionExpiry` — while `createFile` and `updateFile` set only supplied fields. A record carried to the cap by its previous content stayed excluded from the sweep forever, stranding the new object exactly as this PR set out to prevent; a partially failed one started the new object's budget already spent. Both write paths now clear the fields: the budget belongs to the storage a record currently points at. The retry-state fixtures in `file.spec.ts` were seeded through `createFile`, which now clears them, so they drive the real methods the sweep uses. * 🎯 fix: Clear the retry budget only when a retention lifecycle starts Both findings from the review of 8d26f9b, and both are consequences of that commit's reset rather than of the original change. - The reset was unconditional on every `createFile`/`updateFile`, on the reasoning that those paths write content. Two of them do not. `prepareImages{Local,Azure,Firebase}` call `updateFile({ file_id })` with nothing but the id — a TTL touch — every time an existing image is encoded for another chat, and the deferred preview uses the same method to transition `status`. Either handed a stranded record a fresh set of attempts and another give-up notice, on repeat, defeating the cap for the files most likely to be stranded. Gate it on the write actually setting `expiredAt`. The budget belongs to a retention lifecycle: that is the write which starts a new one, it is what `processCodeOutput` supplies when it repurposes a record, and a record with no retention deadline is never swept, so the fields are inert there anyway. - Both retry writes bumped `updatedAt`. `processCodeOutput` falls back to `updatedAt` as the writer-order stamp for records that predate `metadata.sourceDispatchedAt`, so a failed sweep landing mid-harvest read as a newer content writer and the harvest dropped its attachment. Mark them `timestamps: false`, for the reason `claimCodeFile` already does: bookkeeping is not a content write. * 🅿️ refactor: Park exhausted files instead of excluding them Three review rounds in a row found defects in how the give-up cap interacts with record reuse, each in the fix for the last. That is a design error, not a bug list: a permanent exclusion has to be bound precisely to the content lifecycle it was recorded against, and File records outlive their content. `processCodeOutput` repurposes a row for a repeated `(filename, conversationId)`, `createFile`/`updateFile` set only supplied fields, and `getRetentionExpiry` returns `{}` on a lookup failure so the row inherits its old deadline — three separate ways for bookkeeping to survive into a lifecycle it does not describe, each needing its own guard, and the two retry writes needing to be lifecycle-conditional on top. Remove the category instead. `deletionRetryAt` becomes the sweep's only hold, and reaching `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` parks the file for a month rather than excluding it. The bound on the batch is the same — a stranded file costs one slot a month instead of one an hour — but a deadline that outlives its content can only delay the next object, never lose it, so nothing outside the sweep has to reason about this state at all. That deletes more than it adds: - `createFile` and `updateFile` go back to their original form. No reset, so no question of which writes install content, and `prepareImages*` and the deferred preview stop mattering here. - `getExpiredFiles` loses `maxAttempts` and its `$and`; eligibility is one `$or` on the deadline. - The interleaving race between the increment and the deferral degrades from a stranded object to a delayed one. Working through a large backlog is throughput-bound either way: every attempt costs a slot in the bounded batch, so N stranded files need N × `FILE_RETENTION_SWEEP_MAX_ATTEMPTS` passes to settle. Lower that limit when recovering a deployment that has accumulated many.	2026-09-04 15:38:17 -04:00
Danny Avila	c302ae6f35	🪁 fix: Honor Endpoint Drop Params in Parameter Panels (#15610) ... * Remove parameters from UI when parameter is dropped through dropParams * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * Addressed copilot and codex review suggestions * 1. Normalize drop parameter names in client/src/components/SidePanel/Parameters/Panel.tsx Admin-configured dropParams for Azure/OpenAI-compatible custom endpoints use the effective backend field names (maxTokens, topP, frequencyPenalty, presencePenalty), but the panel's filter compared them against the UI's snake_case keys (max_tokens, top_p, etc.), so the controls stayed visible and silently discarded whatever the user set. Added a dropParamsBackendToUIKey map (in packages/data-provider/src/parameterSettings.ts) and normalize each dropParams entry through it before filtering. 2. Apply the same drop-parameter filtering in client/src/components/SidePanel/Agents/ModelPanel.tsx The Agent builder's model panel built its parameter list independently and never consulted endpointsDropParamsMap at all, so it kept offering controls for Azure/custom providers whose values the backend drops. Reused the same resolution logic (including the new backend→UI key normalization) there, sourced from useGetStartupConfig. 3. Remove any escapes from Azure fixtures in packages/api/src/app/config.test.ts Three tests built azure groupMap/modelGroupMap fixtures via ... as any as AppConfig['endpoints'], bypassing type checking for that shape. Replaced them with two typed helpers, createAzureGroupMap and createAzureConfig, built from the existing TAzureConfig/TAzureGroupMap/TAzureModelGroupMap types, so the fixtures are now fully type-checked with no any. * HAL-1081 Deploy librechat open 1. Gate the backend-name alias to OpenAI-compatible parameter sets (packages/data-provider/src/parameterSettings.ts) dropParamsBackendToUIKey had been applied unconditionally, rewriting a dropped topP to top_p even for a custom endpoint whose defaultParamsEndpoint is anthropic/google (or a native bedrock-* endpoint) — where topP is the UI key, so the rewrite broke hiding the control. Replaced the plain map with resolveDropParamsUIKeys(dropParams, endpointKey), which only aliases backend names for OpenAI-compatible endpoint keys (openAI, azureOpenAI, custom, openRouter) and passes native-provider keys through unchanged otherwise. Updated both Panel.tsx and ModelPanel.tsx to call it with overriddenEndpointKey, and added a resolveDropParamsUIKeys test suite in parameterSettings.spec.ts. 2. Prune stale model_parameters when a control becomes hidden (client/src/components/SidePanel/Agents/ModelPanel.tsx) When a parameter an agent already had set gets added to its endpoint's dropParams, the control disappeared but the value stayed in model_parameters and was saved unchanged by composeAgentUpdatePayload — invisible to the user and silently reactivated if the endpoint later stopped dropping it. Added a useEffect, mirroring the conversation panel's existing pruning effect, that strips any model_parameters key no longer present in the currently-visible parameters list. Also fixed a pre-existing test regression (missing useGetStartupConfig mock) and added two tests covering pruning-on-drop and value retention when the control stays visible. * fix: Preserve parameters for unknown agent providers * fix: Sanitize agent parameters on submission * fix: Preserve agent model overrides during pruning --------- Co-authored-by: Marc Amick <MarcAmick@jhu.edu> Co-authored-by: MarcAmick <5194465+MarcAmick@users.noreply.github.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>	2026-09-04 13:52:23 -04:00
Danny Avila	09da878a47	🚰 fix: Throttle Shared Link Reads and Aggregate Audit Findings (#15605) ... * 🪵 fix: Aggregate Audit Findings and Rate Limit Shared Link Reads Audit-mode content filter rules wrote one `logger.info` per matching fragment, and inspection deliberately continues past every finding. A shared conversation full of distinct matching strings therefore produced one log write per fragment, regenerated on every retrieval of `GET /api/share/:shareId` — a public, unauthenticated route with no limiter. The 4,096-entry inspection dedupe set is a memory bound, not an event budget: once full, further values are inspected and logged again. Audit metadata carries no inspected text — only rule, source, field and provenance — so thousands of those writes were byte-identical lines. Findings are now counted inside an aggregation scope and reported once per distinct key with an `occurrences` count when the scope ends: - `assertModelBoundContent` opens a scope when audit rules are configured, bounding one inspection pass (a single message's fragments). - `assertConversationImportContentAllowed` opens the outer scope for import and shared-link snapshots, so per-message inspections nest into one report instead of one per message. - `createShareContentPreflight` spans the shared-file metadata pass too. Nested scopes reuse the outermost aggregation, and outside any scope the previous immediate write is kept. `GET /api/share/:shareId` re-inspects the whole snapshot on every request, so it now carries IP and user limiters like the neighbouring fork route (`SHARE_IP_MAX`/`SHARE_IP_WINDOW`, `SHARE_USER_MAX`/`SHARE_USER_WINDOW`, `SHARE_VIOLATION_SCORE`); the user limiter skips anonymous viewers. * 🔒 fix: Address Codex Findings on Share Audit Aggregation - The aggregation key joined rule fields with a space, but the filter schema allows spaces in custom pattern ids and labels, so `{id: 'a', label: 'b c'}` and `{id: 'a b', label: 'c'}` collided on the same source/field/provenance and merged two rules' counts under one identity. Serialize the tuple instead. - `SHARE_VIOLATION_SCORE` left unset reached `logViolation` as `undefined`, which selects that function's default score of 1 rather than the documented zero. With default ban settings a viewer refreshing a rate-limited shared link would be banned after 20 rejections. Default the score to 0 in code, not only in `.env.example`. - `removePorts` returns a full IPv6 address, so an attacker holding a prefix could rotate the host portion for a fresh bucket on every request — and for anonymous viewers the IP limiter is the only bound. Derive the key through `ipKeyGenerator` so IPv6 clients group by /56.	2026-09-04 12:38:34 -04:00

Danny Avila	770238f22b	🔣 refactor: Replace Mongo Filters With Typed Criteria (#15580) ... * ♻️ refactor: Take Typed Criteria, Not Mongo Filters, for Actions and Assistants `createActionMethods` and `createAssistantMethods` accepted `FilterQuery<T>`, putting Mongoose's query language in the package's public surface: every caller wrote raw Mongo, and no engine other than Mongo could satisfy the signatures. Both now take domain criteria — `ActionQuery` and `AssistantQuery` — naming concepts rather than stored fields, with an array meaning "any of these". A per-domain field map translates them, so `FilterQuery` survives only inside the two translators. `buildFilter` throws on a criterion the field map does not cover. Callers in `api/` are JavaScript and get no compile-time checking, and the server sets `strictQuery`, under which a silently dropped criterion widens the filter instead of narrowing it — an unscoped `findOne` returns an arbitrary document rather than none. Failing closed is the only safe default. `AssistantQuery.avatarFilepath` covers the avatar-authorization lookup, which queries a nested path no plain field name reaches. No behaviour change: every migrated call site produces the same filter as before. * 🧪 test: Update Avatar Authorization Assertion to Typed Criteria `validateImages.spec.js` asserted the old `{ 'avatar.filepath': { $in: [...] } }` call shape for `getAssistant`. The earlier sweep matched on `action_id`, `agent_id` and `assistant_id`, none of which appear in a dotted avatar path, so this one assertion was missed. The `getAgent` assertions in the same file keep the filter shape — that method still takes a `FilterQuery`. * 🔒 fix: Reject Unknown Criteria Before Omitting Undefined Ones `buildFilter` skipped a criterion whose value was `undefined` before checking it against the field map, so a JavaScript caller misspelling a key that happened to carry `undefined` — `deleteActions({ agent_id: maybeId })` — produced `{}` and reached `deleteMany` unscoped. That is the exact failure the guard exists to prevent, defeated by the order of the two checks. Validate every key first, then apply the undefined-omission rule. The lookup is an own-property check so inherited names cannot resolve through the field map's prototype: `{ toString: 'x' }` previously found `Function.prototype.toString`, passed the truthiness test, and wrote a garbage filter key instead of throwing. A recognized criterion left `undefined` is still omitted, so optional parameters keep working. * 🔒 fix: Reject Query Fragments as Criteria and Keep the Translator Internal Three review findings on the criteria translator, all of the same shape: the guard was narrower than the surface it protects. Criterion values are now validated as scalars or lists of scalars. `matchAny` copied any non-array through unchanged, so a JavaScript caller could pass `{ agentId: { $ne: null } }` and have the operator land verbatim in the filter — the fail-open case the field map exists to close. `null` is rejected too; it would have matched documents missing the field entirely. `matchAny`, `buildFilter` and `FieldMap` are no longer re-exported from the package barrel. They emit Mongo, and shipping them as public API undercut the point of the change; they were reachable as `require('@librechat/data-schemas') .buildFilter`. `OneOrMany` moves to `types/query` because the domain query types reference it and it names no engine — which also drops the `types` -> `utils` import. `loadActionSets` names `ActionQuery` through `import()` so the JSDoc type actually resolves.	2026-09-04 11:54:21 -04:00
Danny Avila	a21c7944ee	🏷️ fix: Record the Media Type of Saved Images, Not the Declared One (#15606) ... `saveBase64Image` recorded the media type declared in the incoming data URL while persisting bytes that sharp had re-encoded. Those are not always the same format: sharp rasterizes SVG to PNG, so an image arriving as `image/svg+xml` was stored as `<id>-<name>.svg`, typed `image/svg+xml`, holding PNG bytes. That type is not cosmetic. `encode.js` hands `file.type` to providers verbatim — `media_type` for Anthropic, `inlineData.mimeType` for Google, and the `data:` prefix for OpenAI — so re-attaching such an image sends PNG bytes under a media type the provider does not accept for images, and the request fails. A declared type is also only ever a claim. The same mismatch arises whenever a producer mislabels what it sends, which for MCP tool output means any connected server can decide what the record says about bytes it did not have to match. `resizeImageBuffer` already read the encoded output back to measure it, so it now resolves that metadata to a media type and returns it, and `saveBase64Image` records it in place of the declared one, falling back to the declared type only when sharp reports a format that has no media type of its own. The upload paths were already correct — they record `image/${imageOutputType}`, the format they convert to — so this brings the tool-output path in line with them. `resolveImageMimeType` lives in `packages/api` because AVIF and HEIC share the heif container and are told apart by its compression, which is worth stating once with tests rather than open-coding at each call site.	2026-09-04 11:51:28 -04:00

Marco Beretta	10c5c91594	🎨 feat: Theme-Adaptive SVG Support for Custom MCP and Group Icons (#13817) ... * feat: theme-adaptive SVG support for custom MCP and group icons Custom icons (MCP server iconPath, model spec groupIcon) were rendered as plain <img>, so monochrome SVGs kept fixed dark colors and were nearly invisible in dark theme. Introduce a shared CustomIcon component that detects monochrome SVG glyphs and tints them with currentColor so they follow the active theme, while multi-color SVG logos and raster images keep their original colors. The monochrome decision parses the SVG's color tokens; content is fetched once, cached, and any failure falls back to the original image. Monochrome SVGs render via CSS mask, never inlined, so no SVG markup reaches the DOM. Apply across all custom-icon surfaces: MCP settings cards, the chat MCP dropdown, stacked MCP icons, tool-call headers, and model group icons. Also support SVG in the MCP avatar uploader: add SVG to the accepted file types and sanitize uploaded SVGs with DOMPurify before storing them, and make the dialog preview theme-adaptive via the same component. Add unit tests for SVG detection, monochrome analysis, sanitization, and CustomIcon rendering. * fix: reset adaptive icon tint state when the source changes A reused CustomIcon instance kept the monochrome verdict from a previous source until its effect re-ran, so switching to a raster image or a new multi-color SVG could briefly render it as a currentColor silhouette. Key the resolved verdict to the current source and reset it synchronously during render (seeding from cache when available), so a stale verdict can never tint a different icon. Add hook tests covering the source change. * fix: do not tint custom SVGs that have an opaque background A grayscale SVG with an opaque full-canvas background (for example an exported logo with a white background rect and a black glyph) passed the monochrome check and was drawn through a CSS mask. Masks key off the alpha channel, so the opaque background filled the whole area with the tint color and the icon collapsed into a solid block. Detect a full-canvas opaque background rect and exclude such SVGs from tinting, rendering them with their own colors instead. Transparent single-color and multi-shade glyphs remain tintable. Add tests for the background cases. * fix: detect opaque SVG backgrounds without a viewBox Opaque background detection only read canvas dimensions from the viewBox, so an SVG that declares width and height on the root element but omits the viewBox slipped through and was tinted into a solid block. Fall back to the root svg width and height when no viewBox is present, and match attribute names exactly so stroke-width is not mistaken for the canvas width. Add tests for the no-viewBox cases. * fix: parse comma-separated SVG viewBox values The viewBox regex only accepted whitespace between values, so a valid viewBox like "0,0,24,24" failed to parse and an opaque background went undetected, tinting the icon into a solid block. Accept commas and whitespace as separators. Add a test for the comma-separated case. * refactor: detect SVG tintability with DOMParser instead of regexes The monochrome/tintable decision scraped SVG markup with regexes, which kept missing edge cases (opaque backgrounds, missing or comma-separated viewBox, stroke-width vs canvas width, embedded raster images). Parse the SVG once with DOMParser and inspect real elements and attributes: reject embedded <image>/<foreignObject> content, detect a full-canvas opaque background rect, read the canvas size from the viewBox or root width/height, and gather paint colors from attributes, inline styles, and <style> blocks. Unparseable input is treated as not tintable. Tests cover these cases. * fix: only tint single-tone grayscale SVGs A grayscale SVG can draw its background as a full-canvas path (not just a rect), e.g. a white background path plus a black glyph. The rect-only background check missed that, and the icon flattened to a solid currentColor block under the CSS mask. Tint only when the SVG resolves to a single grayscale tone. Any second tone (a background shape drawn as a path or rect, an accent, or a second shade) now preserves the icon's own colors, which covers full-canvas path backgrounds without per-shape geometry parsing. * fix: count default black fill when detecting tintable SVGs * fix: treat currentColor as a tone and stroked closed shapes as filled * fix: ignore non-rendering template paint and count filled open paths * fix: scan defs and symbol paint rendered through use references * fix: resolve currentColor against fixed color and match style fills for default paint * fix: treat alpha-zero fills as transparent in SVG tint detection * fix: resolve inherited and CSS fill for backgrounds and default paint * fix: resolve CSS currentColor and default-black use instances * fix: count default-filled polylines when detecting tintable SVGs * fix: resolve inherited fill and style/CSS opacity in SVG tint detection * fix: ignore display:none shapes and stop counting CSS color as paint * fix: only count CSS paints that match rendered elements * fix: match root for CSS currentColor and skip unreferenced defs tones * fix: count paint only on rendered shapes and filter hidden CSS currentColor * fix: resolve use-instance currentColor and skip hidden use default fills * fix: resolve CSS paints onto rendered painters and skip overridden use fills * fix: keep checking ancestor opacity after resolving paint opacity * fix: resolve CSS paints by specificity and skip transparent default fills * fix: apply CSS over presentation attributes and follow nested use targets * fix: strip CSS comments, honor visibility, and inherit paint through nested use * fix: skip transparent svg use references * Account for SVG filter colors * fix: propagate outer use color through nested currentColor references * fix: preserve url() id casing and record every nested use chain * fix: preserve SVGs whose filters recolor the source * refactor: detect monochrome icons via canvas pixel sampling Replace the SVG source parser with offscreen-canvas pixel sampling: draw the icon, read pixel data, and treat it as monochrome only when every non-transparent pixel is grayscale within tolerance and the image has some transparency (a fully opaque image would mask to a solid block). Verdicts are cached per src. An explicit monochrome flag on CustomIcon skips detection; sampling is the fallback. Image load failures and canvas taint from non-CORS cross-origin icons fall back to untinted rendering instead of throwing. * harden custom SVG icon handling across security, a11y, and perf Sanitize user-provided MCP iconPath server-side; the client-side DOMPurify pass was bypassable by posting iconPath straight to the API. Adds sanitizeMcpIconPath in @librechat/api (allowlist SVG sanitizer that preserves case-sensitive names) and runs it in the create/update controllers, plus a length cap on iconPath in the shared schema. - gate theme detection to same-origin/data sources so a remote icon is no longer auto-fetched from every viewer's browser - restore forced-colors (High Contrast) visibility and the broken-icon onError fallback for tinted icons - mark redundant icons decorative to avoid screen-reader double reads - base64-encode inlined SVG data URIs and bound the verdict cache - harden the client SVG sanitizer and guard FileReader failures - cover the tinted render branch, sanitizer allowlist, and edge cases * fix: preserve local SVG references while stripping external hrefs The hardened sanitizers dropped <use> and every href outright, blanking self-contained exporter output like <defs><path id="p"/></defs> <use href="#p"/> and gradients inheriting stops via href="#g". Re-allow <use> and href/xlink:href on both sanitizers, restricted to same-document fragments: the client uses a dedicated DOMPurify instance with an afterSanitizeAttributes hook (kept off the shared default instance), and the server mirrors the rule with a sanitize-html tag transform plus an empty allowedSchemes list as a second layer. External, protocol-relative, relative-path, and javascript: hrefs are still stripped, leaving the element inert. * fix: keep xlink namespace and safe filters in the server icon sanitizer The server allowlist stripped xmlns:xlink from the root while keeping xlink:href, leaving an unbound prefix that is a parse error once the icon is stored as an image/svg+xml data URI, so SVG 1.1 exporter output went blank after save. It also dropped <filter>/fe* primitives that the client sanitizer's svgFilters profile allows, so icons relying on effects like feDropShadow lost them between preview and reload. Allow xmlns:xlink and mirror the client's filter allowlist (elements plus their presentation attributes); feImage passes through the existing fragment-only href transform, so external references are still stripped. * fix: require empty pixels for tinting and block external url() references Two issues from review of the icon sanitizer and monochrome detector: - scanMonochrome flagged any pixel below full opacity as transparency, so an SVG that fills the whole canvas with a semi-transparent grayscale wash was tinted and rendered as a solid currentColor block. Require a genuinely empty pixel (alpha at or below the paint threshold) instead. - The fragment-only reference rule only covered href/xlink:href, so a url() in filter/fill/mask/clip-path/style kept external targets like filter="url(https://evil/f.svg#f)". Both sanitizers now strip any attribute carrying a non-fragment url(), preserving local url(#id). * fix: preserve internal SVG stylesheets while scrubbing their references Exporter SVGs that store multi-color paint in an internal <style> block (e.g. .red{fill:#e00} with class="red") lost all styling because the sanitizers dropped <style> outright, so multi-color logos rendered with default paints after upload. Re-allow <style> on both sanitizers and scrub its CSS: strip comments and @import at-rules and rewrite any non-fragment url() to none, keeping local url(#id) paints. These icons only render in inert <img>/CSS-mask contexts isolated from the host page (no script, and no subresource loads once external refs are scrubbed), so a script-free stylesheet is safe to keep; a premature </style> close still has its trailing markup re-sanitized by the parser. * fix: normalize icon value before deciding it is not an SVG data URI A posted iconPath with leading whitespace or C0 controls (e.g. "\n data:image/svg+xml,...") slipped past the anchored data-URI check, so sanitizeMcpIconPath returned it raw while a browser trims the prefix and still renders the SVG, keeping its external <image>/url() and other stripped content. Normalize the value the way URL parsing does, trimming leading/trailing C0 controls and spaces and removing embedded tab/newline, before the SVG check so these variants are sanitized too. * fix: cap sanitized icon length and re-encode as compact base64 The schema length check ran on the input, but sanitizeMcpIconPath then re-encoded the markup with encodeURIComponent, which expands SVG by well over the base64 input size (a 235KB base64 icon became a 374KB percent string). create stored that over-limit value, and editing the server resubmitted the prefilled value and failed MCPServerUserInputSchema. Re-encode the sanitized SVG as base64 (far more compact for angle-heavy markup, which sanitizing can itself grow via explicit close tags) and drop anything still over MAX_MCP_ICON_PATH_LENGTH, so a stored icon can never exceed the cap that a later edit re-validates against. * fix: resolve CSS escapes before stripping external SVG references A literal url(/@import matcher missed CSS-escaped references: a value like style="fill:u\72l(https://attacker/x)" or an escaped @import survived sanitization because the browser un-escapes \72 to r at tokenization time while the regex never saw a url(...). The external reference was then persisted and served to other clients. Un-escape CSS the way a browser does (single pass over \hex and \char escapes) before the url()/@import matchers run, on both the client and server sanitizers. Also scrub the multi-declaration style attribute in place instead of dropping it, so co-located local paint rules survive while escaped external references are neutralized. * fix: re-sanitize after scrubbing style blocks to block markup reintroduction scrubStyleBlocks runs after sanitizeHtml and splices un-escaped CSS back as raw markup, so an escaped sequence like \3c/style\3e\3cimage/\3e (inert text during the first pass) became a real </style><image href> element after unescaping, past the allowlist. Re-run the allowlist over the scrubbed result whenever a <style> block was rewritten, stripping any element the un-escaping surfaced while leaving legit local rules intact. The client sanitizer is unaffected: it sets the scrubbed CSS as a DOM text node, which serializes with < and > escaped, so no element is reintroduced. Added a regression test pinning that behavior too. * fix: make forced-colors icon tint override the inline background color The forced-colors rule for .custom-icon-tint had no !important, so it lost the cascade to the element's inline `background-color: currentColor` and the masked glyph still blanked out in Windows High Contrast — the exact regression the rule was meant to prevent. Verified in a real forced-colors render: without !important the tinted icon is invisible; with it the glyph paints in CanvasText and stays visible. * fix: enforce icon length cap in the sanitizer, not the schema The schema `.max()` on iconPath rejected the whole update at parse time. A server whose stored icon predates the cap (previous versions allowed large data-URI images) re-submits that value from the edit dialog, so the user was locked out of changing any field or clearing the bad icon. Drop the schema `.max()` and enforce MAX_MCP_ICON_PATH_LENGTH in sanitizeMcpIconPath for every value type: an over-cap SVG is compacted or dropped, an over-cap raster/URL is dropped. Editing a server with a pre-existing oversized icon now succeeds and clears the icon instead of failing validation. * fix: decode XML entities and parse quoted URLs in SVG CSS scrubbing Two more bypasses of the CSS reference scrubber, both live once the stored image/svg+xml is parsed by a viewer: - A <style> block reaches the scrubber as raw text, so an entity-encoded reference like &#64;import (or &#x40;import) was never seen as @import; the browser decodes it at render time. Decode XML character references (numeric + the five predefined named) before the matchers run. - The url() regex excluded ')' even inside quotes, so a valid quoted URL like url("https://x/a)b") slipped through. Parse quoted and unquoted URL tokens separately so a ')' inside quotes stays part of the target. Applied to both the server (sanitizeMcpIconPath) and client (sanitizeSvg) scrubbers. Entity decoding also catches an entity-encoded </style> markup breakout, which the re-sanitize pass then strips. * fix: close custom icon review threads * fix: transpile sanitize-html's ESM dependency chain in api jest runs * fix: preserve marker definitions and fragment-only marker references * fix: keep object-cover sizing when tinting masked icons * fix: preserve textPath labels and currentColor color scopes in icon sanitizer * fix: preserve pattern coordinate-system attributes in icon sanitizer Keep patternUnits, patternContentUnits, and patternTransform so patterned SVGs do not fall back to objectBoundingBox after server-side sanitize. * refactor: sanitize icons with one shared DOMPurify policy The server re-implemented DOMPurify's SVG profiles as two hand-written sanitize-html allowlists, so every element and attribute the client kept had to be transcribed by hand, and each miss surfaced as an icon that previewed correctly and then lost its markers, patterns, filters, or xlink binding once stored. Run DOMPurify on jsdom instead and share the config and reference hook with the client, which drops both allowlists. Restrict url() values to same-document fragments on every attribute rather than on the marker properties alone, so external references in fill, stroke, filter, mask, and clip-path are stripped as well. Restore feDropShadow casing after sanitizing. DOMPurify has to parse as HTML, its XML mode drops filter primitives and gradients, and the HTML tag-name adjustment table predates that primitive, so it survived lowercased and left its filter empty once the stored icon was re-parsed as image/svg+xml. * fix: defer jsdom load until MCP icon sanitization jsdom and dompurify were imported at module scope, so every require('@librechat/api') paid their startup cost. Load them on first SVG sanitize instead. * fix: sort type import in MCP icon sanitizer The static-check import sorter wants value imports before type-only imports. Moving the DOMPurify type import after librechat-data-provider clears the drift. * fix: address PR review bot findings chatgpt-codex-connector: - Resolve icon URLs through new URL() instead of trusting a leading slash, so /\attacker.example/icon.svg is no longer treated as same-origin - Check every url() token in an SVG attribute rather than only the first, and reject values carrying a CSS escape that would decode into one - Forbid animateTransform, animateMotion, animateColor, and mpath, which the SVG profile admitted despite the policy intending to remove animation - Preserve the radial-gradient fr attribute the profile omits - Reject multi-tone grayscale in scanMonochrome, which a mask would flatten - Sample at 128px so a small chromatic accent is not averaged away - Settle a stalled icon load after 10s so its in-flight entry is released - Bound the decoded SVG before building a jsdom tree for it - Reject an oversized icon upload with a visible error instead of accepting it and silently clearing it on save * fix: address Codex findings and trim icon sanitizer comments - Bound icon files by size before reading or sanitizing them - Track tone spread across every painted pixel, not only solid ones - Settle monochrome detection on any sampling throw - Use named DOMPurify/JSDOM types and shorten PR comments * fix: percent-decode SVG data URI bodies before base64 decoding * fix: declare the SVG namespace on sanitized icons and keep icon rejections out of form validity	2026-09-04 10:49:43 -04:00
Danny Avila	ee0a51ac19	🪵 fix: Log Code API Auth Header Failures With Request Context (#15592) ... * 🪵 fix: Log Code API Auth Header Failures With Request Context Every Code API tool LibreChat builds — `execute_code`, `bash_tool` and the PTC tools — resolves its auth headers through `codeExecutionAuthHeaders`. When that throws, `@librechat/agents` replaces it with a fixed "Code execution is not authorized" string before either the model or the operator sees it, and the SDK's own console diagnostic carries no request or user id. Log the failure here before rethrowing. Winston attaches requestId, userId and tenantId to every record, so this is the only line that can be correlated with the `[code-env:inject]` events surrounding a failed execution. Rethrowing unchanged keeps the SDK's sanitization intact — the model-facing message does not change. * 🧵 fix: Carry Non-Error Auth Failures Into the Log Message winston folds an `Error` meta's message and stack into `info.message` before any format runs, so an Error cause already survives the plain console format that prints `info.message` alone. A non-Error rejection does not: winston drops a string or plain-object meta from that format entirely, leaving the same generic line the SDK's sanitization produces. Append the cause to the message only when it is not an Error, so the Error path stays free of a duplicated message. A new spec renders both paths through a real winston transport whose format prints nothing but `info.message`, which is what pins the distinction. * 🧯 fix: Keep the Auth Failure Cause Out of Winston Metadata Passing the caught value as positional metadata had three separate failure modes, all measured against real winston. Winston merges object metadata onto the log record, so a rejection carrying `tenantId`, `userId` or `event_name` lands on top of the fields `attachRequestContext` fills in — and that function deliberately keeps an already-present value, so the failure would be attributed to the wrong user or have its identity stripped by a matching event name. An `Error` is no safer: only its custom enumerable properties are copied, which is exactly the reachable set. Any metadata also arms `format.splat()`, which then treats a `%s` in the cause as a substitution token: rejecting with `service said %s unavailable` rendered `service said service said %s unavailable unavailable`. And `String()` throws on a null-prototype object, so an exotic rejection made the catch block throw its own formatting error instead of logging and rethrowing the original. The cause is now derived through a guarded formatter and inlined in the message, with no metadata at all — which is also what makes it visible on the console format that prints `info.message` alone. The rendering spec now runs through `errors()` and `splat()` as well as the bare printf, and restores each transport's previous `silent` value rather than assuming it was false. * 🔑 fix: Keep Signing Material Out of Code API Key Load Failures Node 24's JSON `SyntaxError` quotes an excerpt of the source around the offending token, so a malformed `CODEAPI_JWT_PRIVATE_JWK_JSON` produces `Unexpected token 'M', ..."d":MIIEvgIBAD"... is not valid JSON` — private key material inside an error message, which every caller then logs. The message redaction patterns do not recognize a bare base64 fragment, so nothing downstream would have caught it. `createSigningKey` now converts any load failure into a diagnostic naming the failure and the key format it attempted, and nothing more. That makes the message safe by construction rather than by scrubbing, which matters because the log added in this branch is what would have persisted it. Also guard the `name`/`message` reads in the cause formatter: a proxy can throw from either accessor, which would have replaced the rejection with a formatting error and logged nothing at all. * chore: bump agents sdk	2026-09-04 10:38:49 -04:00
Danny Avila	c00acb36a0	🌌 feat: Add GPT-6 Astra Support (#15567) ... * 🌌 feat: Add GPT-6 Astra Support Registers OpenAI's GPT-6 Astra (`gpt-6-astra`) as a first-class model on the canonical OpenAI endpoint. Every model-specific behavior Astra requires — Responses routing for tool calls, stripping the sampling and logprob parameters it rejects, and substituting the `none`/`minimal` reasoning efforts it does not accept — lands in `@librechat/agents` (danny-avila/agents#506) rather than here. None of it is expressible at configuration time: tools bind after `getOpenAIConfig` runs, and LangChain's request builders emit `temperature`/`top_p` from instance fields regardless of what this layer sets. Keeping it in the SDK also means the routing gate can be the documented rule (tools present) instead of the over-approximation the config-time GPT-5.6 path is forced into. What is left here is registration: - 1,050,000-token context window and 128K max output - Model dropdown (config.ts) and the `OPENAI_MODELS` example - Standard pricing: $10/M input, $1/M cached input, $12.50/M cache writes, $50/M output - The >272K long-context tier, which LibreChat already supports through `premiumTokenValues`/`premiumCacheTokenValues`: 2x input and cache rates and 1.5x output for the full request Batch/Flex (50%) and Fast mode (2x) have no representation in the pricing model today and are not introduced here; they apply per-request rather than per-model, so they need a request-shape signal this layer does not yet carry. Tests pin the pricing against the documented multipliers rather than restating the literals — cache writes as 1.25x input, and the premium tier as 2x/1.5x of standard — plus threshold behavior either side of 272K, and that `gpt-6-astra` resolves to its own key for snapshots and provider-prefixed ids instead of collapsing onto a shorter `gpt-6` match. Resolves #15560 Ref: https://developers.openai.com/api/docs/models/gpt-6-astra Ref: https://developers.openai.com/api/docs/guides/latest-model * 🧪 test: Guard the GPT-6 Astra Max Output Entry [Copilot] The Astra tests asserted the context window but not the 128K max output added alongside it in `anthropicMaxOutputs`' OpenAI counterpart, so that entry could regress silently. The gpt-5.6 tier test above covers both, and the delete-the-fix check showed the gap: removing the source entries failed only the context assertions. Assert `getModelMaxOutputTokens` alongside `getModelMaxTokens`, and fold the snapshot/prefix cases into one loop so both dimensions are covered for every id shape rather than only the bare one. Verified by deleting just the max-output entry: both Astra tests now fail where previously neither did. * 🪧 feat: Declare the First-Party OpenAI Endpoint to the Agents SDK The agents SDK gates GPT-6 Astra's request constraints — Responses-only tool calls, rejected sampling parameters, unsupported reasoning efforts — on knowing it is talking to the first-party OpenAI surface, and defaults them off. It takes that as a declaration rather than inferring it, because a base URL cannot answer the question: only this layer knows whether a URL is a faithful first-party route, a gateway, or a proxy with its own semantics. That decision already exists here, in `isCanonicalOpenAIBaseURL`, used by the GPT-5.6 Responses default. Declaring it from the same checks keeps it in one place instead of duplicating it downstream where the two could drift — and if the endpoint logic ever moves, it moves once. `firstPartyEndpoint` is declared on `OAIClientOptions` alongside the other agents SDK fields this layer already sets (`promptCache`, `_lc_stream_delay`, `includeReasoningContent`), so it typechecks against the current published SDK and is consumed once the SDK release lands. Two backward-compatibility expectations gain the field. That is the intended signal: they assert the full emitted config precisely so a new field cannot slip through unnoticed. * 🗂 fix: Keep GPT-6 Astra Out of the Assistants Catalogs [Codex P2] `sharedOpenAIModels` feeds `defaultModels[assistants]` and `[azureAssistants]` as well as the OpenAI and agents catalogs. Astra serves tool calls only from the Responses API, and the Assistants endpoints do not route through `getOpenAILLMConfig`, so listing it there offered a configuration the provider rejects. Astra now sits in its own `responsesOnlyOpenAIModels` list, spread into the OpenAI and agents catalogs only. Agents keeps it deliberately: that path does go through `getOpenAILLMConfig`. * 🎚 fix: Route GPT-6 Astra to the Responses API at Config Time [Codex P1] `max_tokens` was shaped into `max_completion_tokens` here, from `llmConfig.useResponsesApi`, while the agents SDK switched Astra to the Responses API later at invocation time — so the request reached an endpoint expecting `max_output_tokens` and was rejected. Deciding the API here fixes that, and generalizes: any field whose shape depends on the endpoint has the same problem, so the choice has to precede the shaping. It also lands before Azure replaces `llmConfig.model` with a deployment name, which is the only point that still knows the real model id. Unlike the GPT-5.6 rule above, this does not depend on reasoning parameters. Astra serves tool calls only from Responses, and OpenAI recommends Responses for it generally, so a static decision loses nothing — which was the reason the SDK was deciding it dynamically. The existing guards carry over: OpenRouter, custom gateways, and an explicit `dropParams` opt-out keep their configured path. The agents SDK is still required, for the request shaping Astra needs on either API (danny-avila/agents#506); it no longer decides routing. * 🏷 fix: Record the Served Model Before Azure Overwrites It [Codex P1] `llmConfig.model` is unconditionally replaced with the Azure deployment name, so the agents SDK received an alias and could not tell which model it was talking to — a deployment not literally named `gpt-6-astra` got none of the request shaping Astra requires. Records the real id in `servedModel` immediately before the overwrite, which is the last point that still knows it. The SDK prefers it over `model` when deciding which model-specific constraints apply (danny-avila/agents#506). Set for every first-party Azure request rather than only Astra: "what this deployment serves" is a fact this layer knows and the SDK decides what to do with, and keeping model-specific knowledge out of here is the point of the split. The backward-compatibility expectation gains the field, which is that test doing its job. * 🎛 fix: Do Not Let a reasoning_effort Drop Disable Astra Routing [Codex P1] The Astra routing reused the GPT-5.6 opt-out wholesale, which treats `dropParams: ['reasoning_effort']` as opting out of the Responses API. That holds for the 5.6 default, which routes *because* of reasoning — removing the effort removes its reason to route. Astra's routing is not reasoning-driven, so a rule clearing an unsupported stored effort silently put it back on Chat Completions, where its tool calls fail. Astra now honors only an explicit `useResponsesApi` drop. Reusing the guard without re-deriving whether each clause applied was the error. * ✂️ fix: Scope GPT-6 Astra to the First-Party OpenAI Endpoint [Codex P1 + P2] Two findings, both Azure, resolved by removing the Azure support rather than extending it. Azure's first-party hosts do not satisfy `isCanonicalOpenAIBaseURL`, so a configured `*.openai.azure.com` was neither routed to Responses nor declared first-party; and moving Astra out of `sharedOpenAIModels` also removed it from the Azure chat fallback, since `getOpenAIModels({ azure: true })` resolves through `defaultModels[azureAssistants]`. Both are moot once the scope is right: OpenAI does not document Astra as available on Azure OpenAI. Its model page lists the API and OpenAI's own subscription plans, with no third-party cloud surface. The Azure handling was support for a deployment the model is not documented to reach, and it produced most of the review findings on this branch and its agents SDK counterpart. Routing and the first-party declaration are now scoped to `EModelEndpoint.openAI`, and the Azure-only `servedModel` recording is gone along with its SDK counterpart. Astra staying out of the Azure catalogs is now the intended outcome rather than a regression. * 🚫 fix: Keep Astra Out of the Initial Azure Catalog [Codex P1] `initialModelsConfig` feeds the OpenAI catalog to Azure OpenAI as well, so scoping Astra to the first-party OpenAI endpoint left it advertised on Azure anyway — and being first in the list, it could become the default selection where no prior choice exists. The server's Azure fallback already excludes it, so the client would offer a model the server then rejects. The Azure initial catalog now uses the OpenAI list minus the Responses-only models, following the same scoping decision the routing guard makes. The initial Assistants catalog was already safe: `fitlerAssistantModels` requires `gpt-4` or `gpt-3.5`, which Astra does not match. Pinned that in a test rather than leaving it to a regex written for another purpose. * ⬆️ chore: Bump `@librechat/agents` to 3.7.20 for GPT-6 Astra Constraints	2026-09-04 10:23:29 -04:00

Danny Avila	30cd1c2f2e	🔇 fix: Stop logging an absent create_file target as an error (#15591) ... `create_file` reads its target before writing so it can tell a create from an overwrite, so `readSandboxFile` missing the path is the ordinary case for a create — yet it was reported at error level, through `logAxiosError`, which rendered the sandbox's own `cat: …: No such file or directory` as "An error occurred while setting up the request" plus a stack. Every ordinary file creation emitted an error-level entry claiming a transport fault about a file that was written half a second later, and an operator reading it concluded the file had been lost. Split the two failures `readSandboxFile` was conflating. A request that never completed still goes to `logAxiosError`; a request the sandbox answered with stderr is now classified on that stderr — an absent path logs at debug, and anything else (permission, a broken interpreter) keeps error level with the sandbox's own wording. The thrown error is unchanged, so the authoring flow's create/overwrite decision still reads it the same way. The classifier moves to `packages/api/src/files/code/errors.ts` and is now shared: `handlers.ts` had two near-duplicate copies of it, the narrower of which documented itself as narrower than the broader one without either deriving from the other. Also carry the cause on `[preflightCodeOutputBatch] … could not be inspected`. That warning follows each `create_file` in the same request, and the batch discarded the error entirely — so a Code API that refused the download, one routed to the wrong execution profile, and a file too large to inspect all arrived as the same sentence, and neither this warning nor the one above could be told apart from the failures around them. It goes through `getSafeErrorMetadata`, which is what keeps the upstream message and the artifact's name — both of which can echo submitted content — out of the log.	2026-09-04 09:21:24 -04:00

Danny Avila	9a43362663	🪤 chore: Scope Assistant Tool-Resource Lookups (#15579) ... `DELETE /api/files` looked the assistant up by `id`, but the Assistant schema stores it as `assistant_id`. `api/db/connect.js` sets `strictQuery`, under which Mongoose drops filter keys absent from the schema — so the lookup degraded to `findOne({})` and returned whichever assistant happened to be first in the collection, regardless of owner. The unlink path then read that stranger's `tool_resources` and intersected it with the caller's requested files, so a file the caller named could be unlinked on the strength of another user's assistant record. With an empty collection the same lookup returned `null` and the unguarded `assistant.tool_resources` threw, answering 400 instead of completing the request. Filter on `assistant_id` and guard the dereference. Adds three route tests that mirror the server's `strictQuery` setting, without which the harness cannot reproduce either failure.	2026-09-04 00:14:44 -04:00
Danny Avila	78b320cbbc	🗜️ fix: Bound Conversation Page Size (#15576) ... `GET /api/convos` read its page size as `parseInt(req.query.limit, 10) || 25` and handed it to `getConvosByCursor` unclamped, where it becomes `.limit(limit + 1)`. `?limit=-1` therefore issued `.limit(0)`, which MongoDB reads as no limit at all, and the route returned the caller's entire conversation list in one response; `?limit=999999999` forced the same unbounded fetch. `attachSharedFlags` then amplified it with a second query whose `$in` carried every returned id. Every other list route already clamps, so the fix reuses that shape: the projects handler's local `normalizeLimit` moves to `packages/api/src/utils/query` and both routes share it, and `getConvosByCursor` bounds its own page size so the invariant holds for any caller.	2026-09-03 23:52:36 -04:00

Danny Avila	2d794a0439	💓 fix: Detect Silently Dead Redis Sockets With Deadline-Bounded Heartbeats (#15539) ... * fix: Detect silently dead Redis sockets with deadline-bounded heartbeats A Redis peer can vanish without a FIN or RST (a dropped NAT entry, a proxy failover, a migrated VM). The socket stays `ready` from ioredis's point of view, no error fires, and every command on it waits for the kernel's retransmission timeout — about fifteen minutes at Linux defaults. Observed in production: while the main client's socket was dead, POST /api/agents hung until Cloudflare returned a 524; while the subscriber's socket was dead, every attach failed with "Timed out synchronizing Redis subscription" for sixteen minutes across five conversations. `REDIS_PING_INTERVAL` could not help — it awaits ping() with no deadline, so the probe just joins everything else that is waiting. - Add startRedisHeartbeat: races a PING against a deadline and destroys the socket when the probe goes unanswered, so ioredis reconnects, replays queued commands, and re-subscribes a subscriber's channels. - Destroy the stream rather than disconnect(true), whose FIN a vanished peer never acknowledges; cluster clients fall back to the regular reconnect. - Add createIoRedisSubscriber so every dedicated subscriber gets an error listener and its own heartbeat, and route the generation-stream and both subagent-routing subscribers through it. - Set ioredis keepAlive from REDIS_KEEP_ALIVE (default 10s). - Add REDIS_PING_TIMEOUT, REDIS_SUBSCRIBER_PING_INTERVAL and REDIS_KEEP_ALIVE, documented in .env.example. - Give the fake RESP server a silent mode and a SUBSCRIBE reply so the dead-peer case can be tested against real clients. * fix: Probe each cluster node and refuse a non-positive heartbeat deadline A cluster-level PING is routed to one node, so a healthy reply proved nothing about the other sockets. The heartbeat now resolves its targets each tick — every node for a cluster, the client itself otherwise — and races an independent deadline per target, tearing down only the socket that stops answering. A non-positive deadline disables the heartbeat with a warning instead of forcing a reconnect on every tick, and the single-probe test no longer depends on wall-clock slack.	2026-09-03 09:45:16 -04:00

The client now publishes the inherited seed before the run streams or resumes, and the context-usage handler awaits each snapshot's publish so the write lands before the model call it describes begins. Failures still only log; the pre-run publish is optional-called so bare resume contexts keep working.

The refresh is best-effort and logs on failure like the content refresh beside it.

A live snapshot with nothing left to persist after an earlier publish now writes a neutral record (ratio 1, no tier), since a running job's fields cannot be deleted through the metadata writer, so a Stop no longer persists an earlier non-neutral state onto the response. The pre-run seed publish is unchanged and is told apart from live snapshots by a flag from the context-usage sink.

LibreChat therefore persists only compact state: the calibration ratio, the default agent's tier, and now the per-agent tiers from Run.getFadingTiers(), stored as validated entries so agent IDs never become MongoDB field names and restored onto a null-prototype record for RunConfig.fadingTiers. Truncated messages, canonical tool content, projection provenance and per-message truncation state are never persisted; the SDK's latched flag is stripped on capture. The per-agent map travels everywhere the single tier already did: response contextMeta, event-actor checkpoint state, HITL pause and resume job metadata in both stores, the Stop path, and branch creation. A shared Mongoose definition keeps the message and conversation schemas identical, the zod schema validates entries, and commitAgentEventActorState rejects malformed maps. Comments no longer describe graph messages as truncated; only the provider projection is. Tests cover: tool results and inputs reach the persisted content parts at full size; contextMeta carries exactly the compact tier and calibration fields; a persisted snapshot round-trips into the seeded RunConfig unchanged and prototype-safe; per-agent tiers survive pause, Redis job round-trips, and event-actor context validation.

The inherited context meta is now published onto the job as soon as the parent's state is loaded and awaited at the top of chatCompletion and resumeCompletion, ahead of run creation and the other abortable setup stages, so a Stop during setup still persists the parent's tiers onto the stopped response. The partial response saved when every subscriber disconnects now carries the job's context meta like the Stop and pause paths do. The branch route keeps the source's context meta in the saved message but strips it from the HTTP response, matching client reads.

Each distinct publication is now issued after the previous one settles, in call order, so the newest snapshot is what a Stop reads back. Equal values still share one write.

Both now apply CLIENT_MESSAGE_SELECT, with getMessagesByCursor accepting a select option, so the persisted fading tiers never reach the client through the paginated endpoint; the search-hydration read projects the same way. A turn that loads a parent's context meta but fails before its run exists used to replace the inherited meta with the capture of a missing run, so the persisted error response lost the last valid tiers. Both finalizers now keep the inherited meta when no run was created while a created run's neutral state may still clear it.

A transiently failing write is retried with a short backoff before the publication is reported and forgotten, so a snapshot's model call no longer proceeds on the first rejection while the job holds the previous record. The SDK swallows handler errors, so retrying is the only way to strengthen the fence without failing the turn. A terminal save now supplies contextMeta: null when the finished run has nothing to carry, and saveMessage unsets a previously stored value in that case, so a disconnect snapshot's record cannot outlive the run that completed neutrally.

Search results are built from the hydrated hit minus its server-private contextMeta, since Meilisearch hydration projects every schema field. The per-agent tier entry guard no longer caps the agent ID length: ephemeral agent IDs encode endpoint, model and sender without a bound, and dropping such an entry would let that agent alone re-derive its tier on the next turn. Also formats the publication spec so the static checks pass.

The dependency set is unchanged from 3.7.15; only the package entry moves. Adds an SDK-backed round trip to the fading spec: a first pruner latches an informative tier, `resolveRunContextMeta` reduces it to the persisted shape, and a second pruner seeded from that shape reproduces the first run's projected tool-exchange bytes under instruction and calibration drift, while an unseeded pruner under the same drift relaxes its tier and rewrites them.

The Flash-family handler that PR generalized already carries the shape 3.8 needs, so registering the model is a one-line rule rather than new behavior: it inherits the strip of deprecated sampling params (temperature/topP/topK), the rejected penalty params, and `thinkingBudget`, defaults to `medium` thinking, and — like 3.7 — errors on `minimal`, so an explicit `minimal` is substituted with the nearest supported level, `low`. - Context window (1,048,576) in googleModels; API + cache pricing in tx.ts - Model dropdown (config.ts) and GOOGLE_MODELS examples for both integrations - Register the model in the Flash-family thinking-rule table - Apply the same introductory pricing as 3.6/3.7 Flash ($0.75 in / $3.75 out / $0.075 cached, per 1M), reverting to $1.50 / $7.50 / $0.15 on 2027-01-01; the existing comments at both call sites now name 3.8 alongside 3.6/3.7 - Tests mirroring the 3.7 Flash coverage: thinking default, legacy-param strip, explicit level pass-through, `minimal` substitution, versioned aliases, context window, model-key mapping, and rates Refs #15516 Ref: https://ai.google.dev/gemini-api/docs/models/gemini-3.8-flash Ref: https://ai.google.dev/gemini-api/docs/pricing * 🔧 chore: Update @librechat/agents dependency to version 3.7.15 in package-lock.json and related package.json files	2026-09-02 15:06:40 -04:00
Danny Avila	29f738dea8	⏭️ feat: Honor an Interrupt Before the Model Has Answered (#15491) ... * ⏭️ feat: Honor an Interrupt Before the Model Has Answered An interrupt armed while the model is still thinking sat as "Interrupting" until the entire turn finished, then landed as a terminal continuation. The cause is upstream: the SDK reads `shouldPreempt` once per streamed chunk, and its seal gate requires non-empty text — so a silent provider is never polled at all, and a reasoning-only turn is never sealable. `@librechat/agents` gains a discard-and-restart path for exactly that window (`HOOK_PREEMPT_RESTART_CAPABLE`). This wires the host half: - `GenerationJobManager.subscribePreempt` registers run-scoped wake listeners, notified after an ACCEPTED arm — local or cross-replica, since both land in `armPreemptIds`. Fenced on `createdAt` like every other preempt entry point, and a throwing listener never fails the arm a queued steer depends on. - `createSteerPreemptPoll` hands that channel to the SDK as `StreamPreemption.subscribe`, gated on a new `isSteerPreemptRestartSupported` probe so an SDK that cannot act on a wake is never handed one. The wake is a hint only: `isPreemptRequested` stays the single authority, so the level-triggered contract the seal path depends on is unchanged. Inert until `@librechat/agents` publishes the restart contract — the probe returns false against the pinned 3.7.11 and the run keeps today's behavior. * 🩹 fix: Replay an Already-Armed Preempt on Subscribe Preempt requests are level-triggered, and the window between a job becoming steerable and the SDK installing its model-attempt listener is real. An interrupt landing there was recorded with no callbacks to notify, and on a silent or reasoning-only turn no later chunk poll may ever run — leaving the request to wait out the whole turn, the exact stall this channel removes. `subscribePreempt` now replays an existing arm to the newly registered listener only, after registration: waking the whole set would re-notify runs that already looked, and waking before registration would leave a concurrent arm with nowhere to land. The `createdAt` fence is unchanged and still gates the replay. The SDK also reads the level flag once at each attempt's start, so this is belt-and-braces rather than the sole cover — but it makes the host correct on its own terms instead of resting on when the SDK happens to look. * 🔧 chore: Update @librechat/agents dependency to version 3.7.14 in package-lock.json and related package.json files * 🔧 chore: Update dependencies in package-lock.json and package.json - Bump versions for @humanfs/core (0.19.1 to 0.19.2), @humanfs/node (0.16.6 to 0.16.8), @xmldom/xmldom (0.8.13 to 0.8.15), and qs (6.15.2 to 6.16.0). - Add @humanfs/types (0.15.0) as a new dependency for @humanfs/node. - Update dependencies for side-channel and side-channel-list to their latest versions.	2026-09-02 13:35:52 -04:00
Danny Avila	0219513115	🛑 fix: Forward Run Abort Signal to Foreground Tool Calls (#15517) ... * 🛑 fix: Forward Run Abort Signal to Foreground Tool Calls Stopping a generation left in-flight tool calls running on the far side. For MCP over streamable-http the external server kept burning CPU until the tool finished or timed out, with no `notifications/cancelled` ever sent. The MCP layer was never the problem: `MCPManager.callTool` already spreads `options.signal` into `client.request`, and the SDK's `Protocol.request` sends `notifications/cancelled` the moment that signal aborts. The signal simply never arrived. Agent tools do not execute inside LangGraph's ToolNode — `eventDrivenMode` dispatches `on_tool_execute` and `createToolExecuteHandler` invokes them. The agents SDK puts the run's abort signal on the batch request (`ToolExecuteBatchRequest.signal`, documented as one handlers should forward), but the handler destructured every field except `signal` and built its invoke config without it. `config.signal` was therefore `undefined` in every foreground tool, so `createMCPTool` derived no signal and the SDK registered no abort listener. Forward it. This restores cancellation for all signal-aware foreground tools, not just MCP. The detached background invoke keeps its own controller, since that work deliberately outlives the turn. An aborted call now rejects promptly and resolves an error result rather than hanging, so the abort is logged at debug instead of as a tool error — a user pressing Stop should not spray the error log. * 🔇 fix: Keep Cancelled Tool Calls on the Filtered Path and Out of Error Logs Addresses both findings from the Codex review of 48fded564a. P1 — the cancellation branch returned before `filteredToolOutputResult`, so with tool-output filtering configured an aborted call's error text reached the turn uninspected. Worse, `runSignal.aborted` says the run is over, not that this rejection was the cancellation: an unrelated failure racing the Stop took the same unfiltered exit. Cancellation now only selects the log level; filtering and the result shape are unchanged. P2 — `createMCPTool` logs its own error before wrapping and rethrowing, so every Stop during an MCP call still emitted an error-level MCP entry and could pollute operational alerts. That catch now recognizes the abort and logs at debug; the wrapped message still reaches the turn. Both are covered by tests that fail against the previous commit. * 🎯 fix: Require an Abort-Shaped Error and Spare Shared OAuth Flows Addresses both findings from the Codex review of b3c67082cd. An aborted run signal proves the turn is over, not that the rejection in hand was the cancellation — a permission, OAuth, or upstream failure can reject in the same tick a user presses Stop. Both quiet-log branches now require the error to look like an abort as well, so a real failure racing the Stop stays at error level and visible to operational alerts. `isAbortError` moves to `@librechat/api` and the copy in `abortMiddleware` is retired, keeping one implementation. Its spec pulls the real function through its partial package mock rather than asserting a stub. Forwarding the run signal also reached ActionService, where two of the three OAuth flows are keyed `userId:action_id` and so outlive the run that opened them: a second run for the same action joins the very same record, and the browser's OAuth callback reads its metadata to exchange the code. `monitorFlow` deletes the key when a waiter's signal aborts, so one Stop could strand a concurrent run and discard an authorization the user had already granted. Those two flows no longer take the signal; the run-scoped login flow, keyed by thread and run, still does. Every guard is covered by a test that fails when the guard is removed. * 🧷 fix: Detach the Stopped OAuth Waiter Instead of Dropping Its Signal Addresses the Codex review of d53ff170ab. Withholding the run signal from the shared Action OAuth flows protected concurrent runs and the browser callback, but left this invocation attached to the flow after the Stop. A callback landing late then resumed `_call` straight into `preparedExecutor.execute` — a consequential API request running after the user had already stopped the turn. Handing the signal back is not the answer either, since `monitorFlow` deletes the shared `userId:action_id` key on abort. `detachOnAbort` separates the two: the caller stops waiting the moment the signal aborts, while the shared flow runs on for whoever else needs it — another run, or the callback exchanging its code. Late settlement of the detached work is swallowed rather than surfacing as an unhandled rejection. Both shared flows now use it. The run-scoped login flow keeps the signal directly, as nothing outside its run observes it. * 🪪 fix: Keep an Action OAuth Abort an Abort Addresses two of the three findings from the Codex review of 70fc0782b1. Detaching the stopped waiter left the rejection to be misread on the way out. The refresh catch treated it as a failed refresh and called `requestLogin()`, emitting an OAuth prompt and opening pending authorization state for a turn that had already ended. `requestLogin` and the surrounding auth catch relabelled it `Failed to authenticate OAuth tool` / `Authentication failed`, and the outer catch handed that to `logAxiosError` — so an ordinary Stop produced two error-level entries and returned failure text as the tool's result. Each boundary now lets an abort through unchanged, and the outer catch logs it at debug and rethrows so it stays a cancellation end to end. Deferred: waiter-only cancellation in `FlowStateManager`, so a detached `monitorFlow` stops polling instead of running out the flow's TTL. That poller is bounded at three minutes and lives exactly as long as it does for a waiter that never left, so it changes no lifetime this branch introduced; giving `FlowStateManager` a non-destructive abort mode is its own change, shared with MCP and indexSync. * 🤫 fix: Classify the Abort at the MCPManager Boundary Too Addresses the Codex review of 9bcf1aa57e. `MCPManager.callTool` logs every rejection at error level before rethrowing to `createMCPTool`, so a user Stop still emitted an MCP error from the inner boundary even after the outer one learned to recognize it. The same signal-plus-abort-shape classification now applies here. The review also noted, correctly, that the existing test could not have caught this: it replaces `getMCPManager` wholesale, so it only ever exercised the outer logger. The new cases drive the real manager with a connection whose `client.request` rejects the way the SDK does once a request signal aborts, and cover both the cancellation and a genuine failure racing the Stop. * 🧹 chore: Restore Import Order in the Agents Tool Handler	2026-09-02 13:32:33 -04:00

Danny Avila	d5b2a8580e	📖 feat: Add Claude Fable 5.1 Support (#15512) ... Claude Fable 5.1 (`claude-fable-5-1`, GA 2026-09-01) succeeds Claude Fable 5 at the same input/output prices, with a 1M context window and 128K max output. The Mythos-class helpers added for Fable 5 already match it — `isMythosClassModel` tests `claude-(?:fable|mythos)[-.]?\d`, so adaptive thinking, summarized-display opt-in, sampling omission, 1M context, the 128K output clamp, prompt caching, the Vertex multi-region gate, and the Bedrock PDF exemption all cover 5.1 without a code change. What was missing was registration and pricing. Cache reads are the one rate that differs, and the substring matcher would have silently gotten it wrong: `claude-fable-5-1` falls through to the `claude-fable-5` key, which prices cache hits at the usual 0.1x base input ($1/MTok). Fable 5.1 and Mythos 5.1 price them at 0.025x ($0.25/MTok), so every cache read would have billed 4x — on exactly the long agentic sessions this model is built for. - Register `claude-fable-5-1` in the shared Anthropic list and `global.anthropic.claude-fable-5-1` in the Bedrock list - Add 1M context / 128K output entries for `claude-fable-5-1` and `claude-mythos-5-1` - Add $10/$50 rates and `{ write: 12.5, read: 0.25 }` cache rates for both - Update the `.env.example` and Vertex `librechat.example.yaml` examples - Test that 5.1 resolves to its own key rather than collapsing onto 5.0, across token maps, pricing, cache rates, and Mythos-class detection The three documented breaking changes from Fable 5 need no handling here: LibreChat never sends a forced `tool_choice` on the Anthropic path (the agents SDK omits the param when unset, so the API default `auto` applies); thinking blocks an earlier model can't read are dropped server-side, unbilled; and history is rebuilt from stored content parts rather than replayed signed thinking blocks, so the prefix-binding check has nothing to reject.
