CVE-2026-97731

Versions of MinIO through 7aac2a2 and pgsty/silo before 1233254 are vulnerable to a security flaw where the system fails to verify if all received x-amz-* headers are present in the client-supplied X-Amz-SignedHeaders list. Specifically, the extractSignedHeaders() function in cmd/signature-v4-uti...

EUVD-2026-86510

MinIO through 7aac2a2 does not verify that every x-amz- header present on a request also appears in the client-supplied X-Amz-SignedHeaders list. extractSignedHeaders in cmd/signature-v4-utils.go iterates only the claimed list and never enumerates the headers that actually arrived, and thus a...

CVE-2026-71192

In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control headers X-Copy-From, X-Copy-From-Account from S3 API requests when s3acl=true. An attacker can inject these headers into a signed PUT request targeting their own bucket, causing Swift to perform a...

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...
