information disclosure vulnerability as referenced in the SECURITY-RELEASE-GITLAB-15-7-2-RELEASED advisory.

  - An issue has been discovered in GitLab CE/EE affecting all versions starting from 10.0 before 15.5.7, all
    versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. GitLab allows
    unauthenticated users to download user avatars using the victim's user ID, on private instances that
    restrict public level visibility. (CVE-2022-3870)

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