Quiz and Survey Master (QSM) <= 10.2.2 - Cross-Site Request Forgery to Template Creation

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 10.2.2. This is due to missing or incorrect nonce validation on the qsm_insert_quiz_template_callback() function. This makes it possible for unauthenticated attackers to create templates via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
