PT-2026-99024

SeaweedFS before 4.34 contains a path traversal vulnerability in the S3 gateway DeleteMultipleObjectsHandler that allows authenticated S3 principals with write access to a single bucket to delete arbitrary objects in other tenants' buckets by supplying object keys containing ../ sequences in the...

SUSE CVE-2026-54917

SeaweedFS is a distributed storage system for object storage S3, file systems, and Iceberg tables. Prior to 4.30, the S3 API gateway and the Iceberg REST catalog gateway construct their routers with mux.NewRouter.SkipCleantrue. With path cleaning disabled, a .. segment inside the URL survives...

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...

CVE-2026-58372

A flaw was found in SeaweedFS. An authenticated remote attacker with write access to a single bucket could exploit a path traversal vulnerability in the S3 gateway. By crafting a DeleteObjects XML request body with specific object keys containing directory traversal sequences, the attacker could...

GHSA-W62W-66V9-VVGV SeaweedFS: Path traversal in the S3 and Iceberg REST gateways allows cross-bucket access

Summary The S3 API gateway and the Iceberg REST catalog gateway construct their routers with mux.NewRouter.SkipCleantrue. With path cleaning disabled, a .. segment inside the URL survives routing, so a request such as: GET /bucket-A/../evil-bucket/key is matched as bucket=bucket-A,...
