Overview
contao/core-bundle is an Open Source PHP Content Management System for people who want a professional website that is easy to maintain.
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the RequestTokenListener process. An attacker can perform unauthorized state-changing actions by tricking a logged-in backend user into loading a crafted URL. This is only exploitable if the victim is authenticated in the backend and loads the malicious URL; the actions performed are limited to the modules accessible by that user.
