The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.4.12. This is due to missing capability checks and nonce verification on AJAX actions registered under both wp_ajax_ and wp_ajax_nopriv_ hooks, as the base controller's getPermissions() returns an empty array and neither removeGroup nor clear are added to getNoncedMethods(), causing the authorization gate to unconditionally return true for these actions. This makes it possible for unauthenticated attackers to delete specific records by ID or delete all records from any module's database table by unauthenticated attackers.
