DRUPAL-CONTRIB-2026-291: Composer/drupal/cms_content_sync vulnerability

Q: Who can realistically exploit this issue?

An attacker must already have access to a database dump or read access to the user data table. It is not exploitable without prior database access.

Q: What credential could be exposed?

The affected credential is the password for the system user used when synchronizing content. Unprivileged users may be able to view it if they obtain the required database access.

Q: How can I determine whether I may be affected?

Assess whether unprivileged users or other unauthorized parties can access database dumps or read the user data table. If such access has occurred, treat the synchronization system user's password as potentially exposed.

Updated

This module enables you to share and reuse content across websites.

The module did not sufficiently encrypt the password of the system user used when synchronizing content. This can potentially allow unprivileged users to view the password.

This vulnerability is mitigated by the fact that an attacker must have access to a database dump or database read access to the user data table. This vulnerability is not exploitable without prior database access.
