What the vulnerability does
The Chat by Chatwee plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.3. This is due to missing or incorrect nonce validation on the admin settings page. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Chat by Chatwee versions 2.1.3 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the chat system without the admin's knowledge or consent. The vulnerability requires user interaction—the admin must visit the attacker's page while authenticated.
What an attacker can do
Perform unwanted actions on the chat system by tricking an authenticated admin into visiting a malicious webpage.
Potential impact on your site
An attacker can modify chat settings or perform administrative actions without your permission if you visit a malicious link while logged in.
Conditions required to exploit
The site admin must be logged in and visit an attacker-controlled webpage; no special privileges required.
