A flaw was found in Moodle. The quiz feature, which allows users to add section headings, did not include a necessary security token. This vulnerability, known as Cross-Site Request Forgery (CSRF), could allow a remote attacker to trick an authenticated user into performing unintended actions within the quiz feature without their knowledge or consent. This could lead to unauthorized modifications or disruptions within the quiz.
