Kognetiks Chatbot for WordPress < 2.1.9 - Cross-Site Request Forgery to Authenticated (Subscriber+) Assistant Modification

Description

The Kognetiks Chatbot for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.8. This is due to missing or incorrect nonce validation on the update_assistant, add_new_assistant, and delete_assistant functions. This makes it possible for unauthenticated attackers to modify assistants via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
