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

  • A vulnerability was discovered in GitLab versions before 13.1.10, 13.2.8 and 13.3.4. An unauthorized project maintainer could edit the subgroup badges due to the lack of authorization control.
    (CVE-2020-13313)

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