What the vulnerability does
The Alex User Counter plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.0. This is due to missing nonce validation on the alex_user_counter_function() function. This makes it possible for unauthenticated attackers to update the 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
Alex User Counter versions 6.0 and earlier contain a cross-site request forgery (CSRF) vulnerability. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without their knowledge. The vulnerability requires the victim to visit the attacker's page while authenticated. No confidentiality or availability impact occurs.
What an attacker can do
Perform unwanted actions on the site by tricking an authenticated admin into visiting a malicious webpage.
Potential impact on your site
