Broken access control in TYPO3 fp_newsletter affected releases allows remote attackers to unsubscribe all newsletter subscribers. The deleteAction accepts arbitrary subscription UIDs without sufficient access checks and applies the unsubscribe operation to each referenced record. No authentication is required, and iterating modified UIDs can remove every subscriber from active newsletter delivery.
