Description
The MxChat – AI Chatbot for WordPress plugin for WordPress is vulnerable to Blind Server-Side Request Forgery in all versions up to, and including, 2.4.6. This is due to insufficient validation of user-supplied URLs in the PDF processing functionality. This makes it possible for unauthenticated attackers to make the WordPress server perform HTTP requests to arbitrary destinations via the mxchat_handle_chat_request AJAX action.
