AI Engine < 2.8.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via `mwai_chatbot` Shortcode `id` Parameter

Description

The AI Engine plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the mwai_chatbot shortcode 'id' parameter in all versions up to, and including, 2.8.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
