An issue has been discovered in GitLab CE/EE affecting all versions starting with 18.0 before 18.0.2. Under certain conditions html injection in new search page could lead to account takeover.

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

  - An issue has been discovered in GitLab CE/EE affecting all versions starting with 18.0 before 18.0.2.
    Under certain conditions html injection in new search page could lead to account takeover. (CVE-2025-4278)

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 ae028662-475e-11f0-9ca4-2cf05da270f3 advisory.
