"The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

  - An issue has been discovered in GitLab affecting all versions starting from 15.4 prior to 15.4.4, and 15.5
    prior to 15.5.2. GitLab was not performing correct authentication with some Package Registries when IP
    address restrictions were configured, allowing an attacker already in possession of a valid Deploy Token
    to misuse it from any location. (CVE-2022-3820)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
