What the vulnerability does
The CardGate Payments for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'page' parameter in all versions up to, and including, 3.2.1 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
CardGate Payments for WooCommerce versions 3.2.1 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in a visitor's browser when they interact with a payment page. The vulnerability requires user interaction and can affect other users or the site itself depending on the injection point. Update to a version newer than 3.2.1 to resolve this issue.
What an attacker can do
Inject malicious scripts that run in visitors' browsers when they interact with payment pages.
Potential impact on your site
