Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Typo3/cms, 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

The workspace/ version preview link created by a privileged (backend) user could be abused to obtain certain editing permission, if the admin panel is configured to be shown. A valid preview link is required to exploit this vulnerability.
