Project: Drupal core [1]
Date: 2024-November-20
Security risk: *Critical* 17 ∕ 25
AC:None/A:None/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross Site Scripting

Description: 
Drupal 7 core's Overlay module doesn't safely handle user input, leading to
reflected cross-site scripting under certain circumstances.

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 [3]
   * 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.
