Unauthenticated file read via path traversal
Published Jul 20, 2024 · Updated Aug 2, 2024
Path traversal in Bazarr 1.4.3 allows remote attackers to read arbitrary server files through the Swagger UI static-file endpoint. The endpoint accepts dot-dot path segments after /api/swaggerui/static and resolves them outside its static directory, as shown by a request for /etc/passwd. No authentication or user interaction is required, and the published proof shows disclosure of local files reachable by the Bazarr process.
