GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user holding a specific granular permission to obtain a GitLab Duo Agent Platform token that bypasses governance controls, due to reliance on untrusted input in a security decision.

The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

  - GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.2.8, 19.3 before     19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user     holding a specific granular permission to obtain a GitLab Duo Agent Platform token that bypasses     governance controls, due to reliance on untrusted input in a security decision. (CVE-2026-105458)

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 5518664d-c652-11f1-b273-2cf05da270f3 advisory.
