CVE-2022-4218Public exploitNetwork attack vector

Quiz deletion and copying via missing nonce

Published Dec 2, 2022 · Updated Apr 8, 2026

Cross-Site Request Forgery in Prasunsen Chained Quiz 1.3.2.4 and earlier allows remote attackers to delete or copy quizzes via forged requests. The list_quizzes() function omits WordPress nonce validation, so a request crafted by an attacker is accepted when a logged-in administrator is induced to click a link. The attack requires administrator interaction in a browser; successful requests alter quiz content by deleting or duplicating quizzes, without evidence of broader code execution.
