Cliengo - Chatbot <= 3.0.2 - Missing Authorization to Authorized (Subscriber+) Chatbot Settings Update

The Cliengo – Chatbot plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'update_session' function in all versions up to, and including, 3.0.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the session token of the chatbot.
