prior to 14.6.5, 14.7.x prior to 14.7.4, or 14.8.x prior to 14.8.2. It is, therefore, affected by the following
vulnerabilities:

  - An unauthorized user can steal runner registration tokens using an information disclosure vulnerability by
    using quick commands. (CVE-2022-0735)

  - An unauthorized user can steal environment variables using specially crafted email addresses due to
    improper input validation in sendmail. (CVE-2022-0741)

  - An unauthorized user can trick users into executing arbitrary commands due to inaccurate display of
    Snippet files with special characters. (CVE-2022-0751)

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