View online: https://www.drupal.org/sa-contrib-2026-223 Project: Black Hole [1] Project machine name: black_hole Date: 2026-October-21 Security risk: *Critical* 16 ∕ 25 AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross-site scripting Affected versions: <1.26.0 || >=2.0.0 <2.0.1 CVE IDs: CVE-2026-114526 Description:  The Black Hole theme provides configurable layouts and visual styling for Drupal websites, including support for Font Awesome icons in navigation menus. The theme does not sufficiently sanitize menu link titles before inserting them into HTML class attributes. This vulnerability is mitigated by the requirement that the attacker must be able to create or modify menu link titles, either through menu administration or through content menu settings where permitted. Solution:  Install the latest version: * If you use Black Hole 8.x-1.x, upgrade to Black Hole 8.x-1.26 [3]. * If you use Black Hole 2.0.x, upgrade to Black Hole 2.0.1 [4].
