CVE-2026-71191

In OpenStack Swift through 2.38.0, S3API middleware does not enforce that semantic x-amz- headers are covered by the SigV4 signature on presigned URL requests. An attacker who obtains a presigned PUT URL can inject an unsigned X-Amz-Copy-Source header, causing Swift to perform a server-side copy...

CVE-2026-55874

A flaw was found in SeaweedFS, a distributed storage system. The S3 API gateway in SeaweedFS does not properly validate X-Amz-Copy-Source headers, specifically failing to reject "dot-dot" path segments. This allows an authenticated user, even if scoped to a single bucket, to read objects from oth...
