Description

The AIKCT Engine Chatbot, ChatGPT, Gemini, GPT-4o Best AI Chatbot plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.6.2. This is due to missing or incorrect nonce validation on the update_integration_option() function. This makes it possible for unauthenticated attackers to change the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
