CVE-2026-16648
Description
This module enables you to log the emails sent by Mailer Plus as content entities, so they can be reviewed at Reports > Mail log. The module doesn't sufficiently redact the content of the emails it logs. Account related emails are stored with their one-time login links intact, so any user who can view the log can obtain a one-time login link for any account, including user 1, and use it to log in as that account. This vulnerability is mitigated by the fact that an attacker must have a role with the permission `View Drupal Symfony Mailer log entries`, which in earlier releases was not marked as a restricted permission.
