- 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.
