NVD Description

Note: Versions mentioned in the description apply only to the upstream minio-fips package and not the minio-fips package as distributed by Minimos. See How to fix? for Minimos:latest 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.
