The direct_mail (aka Direct Mail) extension through 5.2.2 for TYPO3 has a missing access check in the backend module, allowing a user (with restricted permissions to the fe_users table) to view and export data of frontend users who are subscribed to a newsletter.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
