vulnerabilities, including the following:

  - Reflected XSS vulnerability in Micro Focus Application Automation Tools Plugin - Jenkins plugin. The
    vulnerability affects all version 6.7 and earlier versions. (CVE-2021-22510)

  - Improper Certificate Validation vulnerability in Micro Focus Application Automation Tools Plugin - Jenkins
    plugin. The vulnerability affects version 6.7 and earlier versions. The vulnerability could allow
    unconditionally disabling of SSL/TLS certificates. (CVE-2021-22511)

  - Cross-Site Request Forgery (CSRF) vulnerability in Micro Focus Application Automation Tools Plugin -
    Jenkins plugin. The vulnerability affects version 6.7 and earlier versions. The vulnerability could allow
    form validation without permission checks. (CVE-2021-22512)

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