GitLab has remediated an issue in GitLab CE/EE affecting all versions from 11.10 before 18.8.7, 18.9 before 18.9.3, and 18.10 before 18.10.1 that could have allowed an authenticated user to perform unauthorized actions on merge requests in other projects due to improper access control during cross-repository operations.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - GitLab has remediated an issue in GitLab CE/EE affecting all versions from 11.10 before 18.8.7, 18.9     before 18.9.3, and 18.10 before 18.10.1 that could have allowed an authenticated user to perform     unauthorized actions on merge requests in other projects due to improper access control during cross-     repository operations. (CVE-2026-2726)

Note that Nessus relies on the presence of the package as reported by the vendor.

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 b933083e-2b2e-11f1-b60a-2cf05da270f3 advisory.
