* fix: sanitize artifact filenames to prevent path traversal in code output * test: Mock sanitizeFilename function in process.spec.js to return the original filename - Added a mock implementation for the `sanitizeFilename` function in the `process.spec.js` test file to return the original filename, ensuring that tests can run without altering the filename during the testing process. * fix: use path.relative for traversal check, sanitize all filenames, add security logging - Replace startsWith with path.relative pattern in saveLocalBuffer, consistent with deleteLocalFile and getLocalFileStream in the same file - Hoist sanitizeFilename call before the image/non-image branch so both code paths store the sanitized name in MongoDB - Log a warning when sanitizeFilename mutates a filename (potential traversal) - Log a specific warning when saveLocalBuffer throws a traversal error, so security events are distinguishable from generic network errors in the catch * test: improve traversal test coverage and remove mock reimplementation - Remove partial sanitizeFilename reimplementation from process-traversal tests; use controlled mock returns to verify processCodeOutput wiring instead - Add test for image branch sanitization - Use mkdtempSync for test isolation in crud-traversal to avoid parallel worker collisions - Add prefix-collision bypass test case (../user10/evil vs user1 directory) * fix: use path.relative in isValidPath to prevent prefix-collision bypass Pre-existing startsWith check without path separator had the same class of prefix-collision vulnerability fixed in saveLocalBuffer. |
