installed on the remote host is prior to 7.133.11. It is, therefore, affected by a
privilege escalation vulnerability.

  - JFrog Artifactory (Self Hosted) versions before 7.133.11 are vulnerable to a
    privilege escalation attack due to a validation check of the token
    signature/issuer and not the token's scope. (CVE-2026-42016)

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