Unauthenticated Arbitrary File Upload in Chat AI with Dispatcher WordPress Plugin

Executive Summary

This vulnerability is an unauthenticated arbitrary file upload flaw in the WordPress plugin 'Chat AI with Dispatcher' versions before 2.4. It occurs because the plugin does not properly validate uploaded files and relies only on a client-supplied content type, which can be spoofed.
