vulnerabilities:

  - Vulnerable versions of Jenkins allow users to cancel queue items and abort builds of jobs for which they
    have Item/Cancel permission even when they do not have Item/Read permission. (CVE-2021-21670)

  - Vulnerable versions of Jenkins do not invalidate the previous session on login and is, therefore,
    vulnerable to session fixation attacks. (CVE-2021-21671)

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