  - In all versions of GitLab CE/EE since version 8.0, an attacker can set the pipeline schedules to be active
    in a project export so when an unsuspecting owner imports that project, pipelines are active by default on
    that project. Under specialized conditions, this may lead to information disclosure if the project is
    imported from an untrusted source. (CVE-2021-39895)

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