CVE-2026-94368
A flaw was found in the signature verification logic of noobaa-core, the core component of the NooBaa Multicloud Object Gateway. The issue occurs when the service processes S3 presigned URLs using Signature Version 4 SigV4. Due to improper validation, the service fails to reject requests containi...
CVE-2026-94368
NooBaa-core , the core component of the NooBaa Multicloud Object Gateway , contains a flaw in its SigV4 signature verification logic. When processing S3 presigned URLs, the service drops unsigned x-amz- headers from the signature calculation instead of rejecting them. An attacker holding a valid ...

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-2026-71191
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...
