NVD Description

Note: Versions mentioned in the description apply only to the upstream minio package and not the minio package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

MinIO is a high-performance object storage system. Prior to version RELEASE.2026-03-26T21-24-40Z, a flaw in extractMetadataFromMime() allows any authenticated user with s3:PutObject permission to inject internal server-side encryption metadata into objects by sending crafted X-Minio-Replication-* headers on a normal PutObject request. This issue has been patched in version RELEASE.2026-03-26T21-24-40Z.
