## Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the org.xwiki.contrib:discussions-server package. The root cause is that the message deletion endpoint is implemented using a GET request and lacks proper CSRF token validation. An attacker can exploit this by inducing an authenticated user to visit a malicious URL or web page, triggering a forged request that deletes messages on the user's behalf. This vulnerability is addressed in version 2.0-rc-1.
