2.222.43.0.3 rev2, 2.249.x prior to 2.249.30.0.3 rev2, or 2.x prior to 2.277.1.2 rev2. It is, therefore, affected by
multiple vulnerabilities, including the following:

  - An incorrect permission check in Jenkins Matrix Authorization Strategy Plugin 2.6.5 and earlier allows
    attackers with Item/Read permission on nested items to access them, even if they lack Item/Read permission
    for parent folders. (CVE-2021-21623)

  - An incorrect permission check in Jenkins Role-based Authorization Strategy Plugin 3.1 and earlier allows
    attackers with Item/Read permission on nested items to access them, even if they lack Item/Read permission
    for parent folders. (CVE-2021-21624)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Libvirt Agents Plugin 1.9.0 and earlier
    allows attackers to stop hypervisor domains. (CVE-2021-21627)

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