The Layout Builder module doesn’t sufficiently sanitize block labels in certain scenarios, which can lead to a cross-site scripting (XSS) vulnerability.
This is mitigated by the fact that both the attacker and the targeted user need to be using the Layout Builder editing interface.
This vulnerability affects the following application versions:
- Drupal 8.7.0
- Drupal 8.7.1
