Project: Drupal core [1]
Date: 2025-March-19
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross Site Scripting

Affected versions: >= 8.0.0 < 10.3.14 || >= 10.4.0 < 10.4.5 || >= 11.0.0 <
11.0.13 || >= 11.1.0 < 11.1.5
Description: 
Drupal core Link field attributes are not sufficiently sanitized, which can
lead to a Cross Site Scripting vulnerability (XSS).

This vulnerability is mitigated by that fact that an attacker would need to
have the ability to add specific attributes to a Link field, which typically
requires edit access via core web services, or a contrib or custom module.

Sites with the Link module disabled or that do not use any link fields are
not affected.

Solution: 
Install the latest version:

  * If you use Drupal 10.3.x, update to Drupal 10.3.14 [3]
  * If you use Drupal 10.4.x, update to Drupal 10.4.5 [4]
  * If you use Drupal 11.0.x, update to Drupal 11.0.13 [5]
  * If you use Drupal 11.1.x, update to Drupal 11.1.5 [6]

All versions of Drupal prior to 10.3 are end-of-life and do not receive
security coverage from the Drupal Security Team.
