GitLab has remediated an issue in GitLab CE/EE affecting all versions from 12.10 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3 that could have allowed an unauthenticated user to cause denial of service due to improper input validation of JSON payloads.

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 12.10 before 18.8.9, 18.9     before 18.9.5, and 18.10 before 18.10.3 that could have allowed an unauthenticated user to cause denial of     service due to improper input validation of JSON payloads. (CVE-2026-1092)

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 099d4998-33cc-11f1-a7d1-2cf05da270f3 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.
