In plain words
The Black Hole theme does not properly sanitise menu link titles before inserting them into HTML class attributes. An attacker able to create or modify those titles could insert unsafe content into those attributes. This requires access through menu administration or content menu settings where permitted.
Am I affected?
Find drupal/black_hole and its version in composer.lock. The advisory does not give affected version ranges, but lists 1.26.0 and 2.0.1 as fixed. Check who can create or modify menu link titles through menu administration or permitted content menu settings.
What to do
Check which version you have, then update to a fixed release for your branch (1.26.0, 2.0.1):
composer show drupal/black_hole | grep versions
composer update drupal/black_holeIf your version constraint in composer.json keeps you below a fixed release, raise it first. Whether your configuration is affected, and the exact version ranges, are in the advisory itself.
If you cannot update yet
The advisory says the 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.
The advisory's 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.
