## Description

The FunnelKit Automations plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.5.2 due to the plugin's rest_authentication_errors filter clearing all REST authentication errors, including WordPress core's invalid cookie nonce error, whenever the attacker-controlled request URL contained a whitelisted plugin namespace, even when a different route was actually dispatched. This makes it possible for unauthenticated attackers to perform arbitrary REST API actions, such as creating new administrator accounts, as a logged-in administrator via a forged request, provided they can trick the administrator into performing an action such as clicking a link or visiting a malicious page.
