CVE-2026-71191

OpenStack Swift (through 2.38.0) is affected by a vulnerability in the S3API middleware where presigned URL requests do not ensure that semantic x-amz-* headers are covered by the SigV4 signature. An attacker with a presigned PUT URL can inject an unsigned X-Amz-Copy-Source header, triggering a s...
