  - An issue has been discovered in GitLab CE/EE affecting all versions starting from 15.4 before 15.5.7, all
    versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. Due to the
    improper filtering of query parameters in the wiki changes page, an attacker can execute arbitrary
    JavaScript on the self-hosted instances running without strict CSP. (CVE-2022-3573)

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