Technical details
The XML grade import feature in Moodle lacks proper CSRF token validation, allowing an attacker to forge requests from an authenticated user's browser. An authenticated user with grade management permissions is vulnerable if they visit a malicious page under the attacker's control. The attacker can set or overwrite arbitrary student grades without the user's knowledge or consent.
