CVE-2022-4021Network attack vector

Administrator setting changes via missing nonce

Published Nov 16, 2022 · Updated Apr 8, 2026

Cross-Site Request Forgery in Permalink Manager Lite 2.2.20.1 and earlier allows remote attackers to change plugin settings via forged requests. The extra_actions function accepts requests without correctly validating a WordPress nonce, permitting changes to permalinks and site maps when an administrator is induced to click an attacker-controlled link. The attack is unauthenticated but requires administrator interaction, and the demonstrated consequence is unauthorized configuration modification.
