An authorization bypass vulnerability in the TYPO3 CMS recycler module enables authenticated attackers to perform unauthorized data deletion, potentially leading to complete site unavailability.

This vulnerability is a missing authorization flaw (CWE-862) occurring within the recycler module. It allows any authenticated backend user to bypass permission checks and delete records from any database table defined in the Table Configuration Array (TCA), regardless of their assigned access rights.

The ability for an authenticated user to purge arbitrary database tables poses a severe risk of data loss and service disruption. With a CVSS score of 8.1, this high-severity flaw could lead to permanent data destruction, significant operational downtime, and potential regulatory implications regarding data integrity. An attacker with standard backend access could effectively render the entire website non-functional by deleting core content or configuration tables.

Immediate Action: Upgrade the TYPO3 CMS installation to the patched versions: 10.4.55, 11.5.49, 12.4.41, 13.4.23, or 14.0.2.

Proactive Monitoring: Audit backend user activity logs for unusual deletion patterns or mass database operations initiated by non-administrative accounts.

Compensating Controls: Restrict access to the backend recycler module for all users who do not require such functionality as part of their standard operational duties.

Public Exploit Available: No

Given the severity of potential data loss, administrators must prioritize the application of vendor-supplied patches immediately. Organizations should verify that their internal access control policies are strictly enforced and that only necessary personnel have access to administrative modules like the recycler. Failure to address this vulnerability leaves the platform susceptible to malicious data destruction by any compromised or rogue backend account.
