Kognetiks Chatbot for WordPress <= 2.1.7 - Missing Authorization to Authenticated (Subscriber+) Assistant Deletion

The Kognetiks Chatbot for WordPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the delete_assistant() function in all versions up to, and including, 2.1.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete GTP assistants.
