MinIO RELEASE.2022-07-24T01-54-52Z < RELEASE.2026-04-14T21-32-45Z Path Traversal (CVE-2026-42600)

medium Nessus Plugin ID 321446

Synopsis

The remote host is affected by a path traversal vulnerability.

Description

The version of MinIO installed on the remote host is RELEASE.2022-07-24T01-54-52Z or later but prior to 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.

Solution

Upgrade to MinIO version RELEASE.2026-04-14T21-32-45Z or later.
