Description
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.
