An issue was discovered in powermail extension through 12.3.5 for TYPO3. It fails to validate the mail parameter of the confirmationAction, resulting in Insecure Direct Object Reference (IDOR). An unauthenticated attacker can use this to display the user-submitted data of all forms persisted by the extension. This can only be exploited when the extension is configured to save submitted form data to the database (plugin.tx_powermail.settings.db.enable=1), which however is the default setting of the extension. The fixed versions are 7.5.0, 8.5.0, 10.9.0, and 12.4.0

An issue was discovered in powermail extension through 12.3.5 for TYPO3. Several actions in the OutputController can directly be called, due to missing or insufficiently implemented access checks, resulting in Broken Access Control. Depending on the configuration of the Powermail Frontend plugins, an unauthenticated attacker can exploit this to edit, update, delete, or export data of persisted forms. This can only be exploited when the Powermail Frontend plugins are used. The fixed versions are 7.5.0, 8.5.0, 10.9.0, and 12.4.0.
