Content Moderation Notifications - Moderately critical - Information disclosure - SA-CONTRIB-2023-047

Project: Content Moderation NotificationsDate: 2023-September-27Security risk: Moderately critical 11∕25 AC:Complex/A:User/CI:Some/II:None/E:Proof/TD:AllVulnerability: Information disclosureAffected versions: >=3.0.0 <3.6.0Description: This module enables notifications to be sent to all users of a particular role, or to the content's author when a piece of content is transitioned from one state to another via core's content_moderation module.
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.
