"According to its self-reported version, the instance of Drupal running on the remote web server is 9.3.x prior to 9.3.22
or 9.4.x prior to 9.4.7. It is, therefore, affected by a vulnerability.

  - Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to
    3.4.3 encounter an issue when the filesystem loader loads templates for which the name is a user input. It
    is possible to use the `source` or `include` statement to read arbitrary files from outside the templates'
    directory when using a namespace like `@somewhere/../some.file`. In such a case, validation is bypassed.
    Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such template names. There are no known
    workarounds aside from upgrading. (CVE-2022-39261)

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