An issue has been discovered in GitLab CE/EE affecting all versions from 15.10 before 18.0.5, 18.1 before 18.1.3, and 18.2 before 18.2.1 that, under specific circumstances, could have potentially allowed a successful attacker to trigger unintended content rendering leading to XSS.

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 15.10 before 18.0.5, 18.1 before     18.1.3, and 18.2 before 18.2.1 that, under specific circumstances, could have potentially allowed a     successful attacker to trigger unintended content rendering leading to XSS. (CVE-2025-4700)

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 5683b3a7-683d-11f0-966e-2cf05da270f3 advisory.
