Only sites with the Overlay module enabled are affected by this vulnerability.Solution: Install the latest version:

• If you are using Drupal 7, update to Drupal 7.102
• Sites may also disable the Overlay module to avoid the issue.

Drupal 10 and Drupal 11 are not affected, as the Overlay module was removed from Drupal core in Drupal 8.Reported By:
