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. From RELEASE.2022-07-24T01-54-52Z to before RELEASE.2026-04-14T21-32-45Z, A path traversal vulnerability in MinIO's ReadMultiple internode storage-REST endpoint allows a caller holding the cluster root JWT to read files from outside the configured drive roots, bounded only by the MinIO process UID. The attacker sends POST minio/storage/{drivePath}/v63/rmpl with a msgpack-encoded body carrying ../ sequences in the Bucket field. The server opens the resulting path via os.OpenFile with O_RDONLY|O_NOATIME and returns its contents in the msgpack response stream. This vulnerability is fixed in RELEASE.2026-04-14T21-32-45Z.
