Pure Chat – Live Chat Plugin & More! < 2.23 - Cross-Site Request Forgery

Description

The Pure Chat plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.22. This is due to missing or incorrect nonce validation on the pure_chat_update function. This makes it possible for unauthenticated attackers to update chat details via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
