| Doc Text: |
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 other buckets through server-side copy operations. The vulnerability results in unauthorized information disclosure across storage buckets.
