Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Jweiland/events2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue was discovered in the events2 (aka Events 2) extension before 8.3.8 and 9.x before 9.0.6 for TYPO3. Missing access checks in the management plugin lead to an insecure direct object reference (IDOR) vulnerability with the potential to activate or delete various events for unauthenticated users.
