An issue has been discovered in GitLab CE/EE affecting all versions from 18.1 before 18.1.4, and 18.2 before 18.2.2 that could have allowed authenticated users to achieve account takeover by injecting malicious HTML into work item names.

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 from 18.1 before 18.1.4, and 18.2     before 18.2.2 that could have allowed authenticated users to achieve account takeover by injecting     malicious HTML into work item names. (CVE-2025-6186)

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 7bfe6f39-78be-11f0-9d03-2cf05da270f3 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.
