Project: Drupal coreDate: 2025-March-19Security risk: Moderately critical 13 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:DefaultVulnerability: Cross Site ScriptingAffected versions: >= 8.0.0 < 10.3.14 || >= 10.4.0 < 10.4.5 || >= 11.0.0 < 11.0.13 || >= 11.1.0 < 11.1.5Description: 

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:

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