RELEASE.2026-04-14T21-32-45Z. It is, therefore, affected by a path traversal vulnerability:

  - 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. (CVE-2026-42600)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported
version number.");
