The module doesn't sufficiently check access to content when sending notifications. This vulnerability is mitigated by the fact that an attacker must have been assigned to receive notifications for the given content. Additionally, only data sent in the email is visible, so the attacker cannot access the content on the site. Solution:  Install the latest version: * If you use the Content Moderation Notifications module for Drupal 8.x, upgrade to Content Moderation Notifications 8.x-3.6 [3].
