Doc Text:
A flaw was found in Moodle. The regrade action in the quiz overview report did not include the necessary token, leading to a Cross-Site Request Forgery (CSRF) vulnerability. A remote attacker could exploit this by tricking an authenticated user into performing unintended actions, such as regrading quiz attempts, without their explicit consent.
