SeaweedFS <= 4.29 - Path Traversal File Write

SeaweedFS versions through 4.29 build the S3 API and Iceberg REST catalog routers with mux.NewRouter.SkipCleantrue, which disables URL path cleaning. A .. segment in the request path therefore survives routing and reaches the handlers unnormalised, so a request such as PUT...

GHSA-56WQ-X3WV-3FF4 SeaweedFS: Path traversal in the S3 gateway X-Amz-Copy-Source header allows cross-bucket object read

Summary The SeaweedFS S3 API gateway did not reject .. path segments in the X-Amz-Copy-Source header used by CopyObject and UploadPartCopy. The request URL path was hardened against traversal in 4.30 CVE-2026-54917, but the copy-source header was only checked for emptiness, so a .. segment in the...
