Description
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.7 via the 'mediaId' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to access and retrieve the transcribed contents of private audio attachments belonging to other users, including Administrators, via a supplied attachment ID. This vulnerability requires the Public API module to be enabled in the plugin settings; when disabled, the REST route is absent and the endpoint returns HTTP 404.
