View online: https://www.drupal.org/sa-core-2025-001

Project: Drupal core [1]
Date: 2025-February-19
Security risk: *Critical* 17 ∕ 25
AC:Basic/A:None/CI:Some/II:Some/E:Proof/TD:All [2]
Vulnerability: Cross site scripting

Affected versions: >= 8.0.0 < 10.3.13 || >= 10.4.0 < 10.4.3 || >= 11.0.0 <
11.0.12 || >= 11.1.0 < 11.1.3
Description: 
Drupal core doesn't sufficiently filter error messages under certain
circumstances, leading to a reflected Cross Site Scripting vulnerability
(XSS).

Sites are encouraged to update. There are not yet public documented steps to
exploit this, but there may be soon given the nature of this issue.

This issue is being protected by Drupal Steward [3]. Sites that use Drupal
Steward are already protected, but are still encouraged to upgrade in the
near future.

Solution: 
Install the latest version:

 * If you use Drupal 10.3.x, update to Drupal 10.3.13 [4]
 * If you use Drupal 10.4.x, update to Drupal 10.4.3 [5]
 * If you use Drupal 11.0.x, update to Drupal 11.0.12 [6]
 * If you use Drupal 11.1.x, update to Drupal 11.1.3 [7]

All versions of Drupal 10 prior to 10.3 are end-of-life and do not receive
security coverage. (Drupal 8 [8] and Drupal 9 [9] have both reached
end-of-life.)
