GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.7 before 18.11.7, 19.0 before 19.0.4, and 19.1 before 19.1.2 that under certain conditions could have allowed an authenticated user to execute arbitrary scripts in another user's browser session due to improper sanitization of user-supplied input.

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 15.7 before 18.11.7, 19.0     before 19.0.4, and 19.1 before 19.1.2 that under certain conditions could have allowed an authenticated     user to execute arbitrary scripts in another user's browser session due to improper sanitization of user-     supplied input. (CVE-2026-13320)

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 84ce0c0c-7b4e-11f1-9c40-2cf05da270f3 advisory.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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