Description

A flaw was found in Moodle. The XML grade import feature lacks proper Cross-Site Request Forgery (CSRF) token validation. By tricking an authenticated user with grade management permissions into visiting a malicious webpage, an attacker can trigger unauthorized requests on the victim&#39;s behalf. This flaw allows a remote attacker to set or overwrite student grades without authorization.
