Vulnerability: Cross Site Scripting

Description: 
Under certain circumstances the File module/subsystem allows a malicious user
to upload a file that can trigger a cross-site scripting (XSS) vulnerability.

Solution: 
   * If you are using Drupal 8.6, update to Drupal 8.6.13 [3].
   * If you are using Drupal 8.5 or earlier, update to Drupal 8.5.14 [4].
   * If you are using Drupal 7, update to Drupal 7.65 [5].

Versions of Drupal 8 prior to 8.5.x are end-of-life and do not receive
security coverage.
