multiple vulnerabilities, including the following:

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Configuration Slicing Plugin 1.51 and earlier
    allows attackers to apply different slice configurations. (CVE-2021-21617)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Claim Plugin 2.18.1 and earlier allows
    attackers to change claims. (CVE-2021-21620)

  - Jenkins Support Core Plugin 2.72 and earlier provides the serialized user authentication as part of the
    'About user (basic authentication details only)' information, which can include the session ID of the user
    creating the support bundle in some configurations. (CVE-2021-21621)

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