What the vulnerability does
The Clik stats plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` parameter in all versions up to, and including, 0.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Clik stats versions 0.8 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the application. An attacker can craft a malicious link that, when visited by a site user, executes arbitrary JavaScript in the victim's browser. This can lead to session hijacking, credential theft, or defacement of the site interface.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser to steal session data or credentials.
Potential impact on your site
Site users visiting malicious links could have their sessions compromised or credentials stolen through injected scripts.
Conditions required to exploit
Attacker must trick a user into clicking a malicious link or visiting a crafted page (user interaction required).
