Project: Drupal coreDate: 2026-July-15Security risk: Moderately critical 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Cross-site scriptingAffected versions: >=11.3.0 <11.3.14 || >=11.4.0 <11.4.4 || 11.2.*CVE IDs: CVE-2026-15917Description: Drupal core 11.2 and above integrate the HTMX JavaScript library.
Drupal core's XSS filter does not sufficiently sanitize certain HTMX attributes, which can lead to a cross-site scripting (XSS) vulnerability.
The vulnerability is mitigated by the fact an attacker must be able to insert HTML with specific attributes.Solution: Install the latest version:
Drupal 11
If you use Drupal 11.4.x, update to Drupal 11.4.4.
If you use Drupal 11.3.x, update to Drupal 11.3.14.
Drupal 11.2.x and below are end-of-life and do not receive security coverage.
Drupal 10
Drupal 10 core is not affected. However, certain contributed modules may be affected, so a Drupal 10.6 fix is included as hardening.
Drupal 8 and Drupal 9 have both reached end-of-life.Reported By:
