"According to its self-reported version, the instance of Drupal
running on the remote web server is 8.7.4. It is, therefore,
affected by an access bypass condition when the experimental
Workspaces module is enabled. 

Note this vulnerability does not affect any release other
than Drupal 8.7.4. Drupal 8.7.3 and earlier, Drupal 8.6.x
and earlier, and Drupal 7.x are not affected.

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