CVE-2022-4220 Information

Description

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 list_questions() function. This makes it possible for unauthenticated attackers to delete questions from quizzes via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
