CVE-2022-4219

The Chained Quiz plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.2.4. This is due to missing nonce validation on the manage() function. This makes it possible for unauthenticated attackers to delete submitted quiz responses via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
