SeaweedFS: Unauthenticated filer IAM gRPC service grants S3 administrative control

Impact The filer registered the IAM gRPC service SeaweedIdentityAccessManagement with no authentication. Any client able to reach the filer gRPC port could invoke IAM RPCs — CreateUser, CreateAccessKey, PutUserPolicy, and related calls — to mint credentials and grant itself S3 administrative...

BIT-SEAWEEDFS-2026-77611 SeaweedFS: Authenticated S3 object-scope bypass in PutObjectAcl allows overwriting a different object with the same basename

SeaweedFS is a distributed storage system for files and blobs. In versions prior to 4.40, an authenticated S3 principal with permissions scoped to a nested object key can overwrite a different object outside that scope by calling PutObjectAcl on the key it is allowed to access. The handler...

BIT-SEAWEEDFS-2026-77298 SeaweedFS S3 OIDC Bearer authentication bypasses IAM role trust policy

SeaweedFS is a distributed storage system for files and blobs. In versions 4.39 and earlier, the S3 API accepts an external OIDC JWT sent directly in the Authorization header and maps it to an IAM role without enforcing that role's trust policy, so a federated user can assume a role they are not...
