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

  • A stored Cross-Site Scripting vulnerability in the Jira integration in all GitLab versions starting from 13.9 before 14.0.9, all versions starting from 14.1 before 14.1.4, and all versions starting from 14.2 before 14.2.2 allows an attacker to execute arbitrary JavaScript code on the victim’s behalf via malicious Jira API responses (CVE-2021-22261)

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