    versions starting from 14.10 before 14.10.4, all versions starting from 15.0 before 15.0.1. It may be

    REST API, even after their group owner enabled a setting to prevent members from being added to projects
    within that group. (CVE-2022-1783)

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