What the vulnerability does
The WooCommerce Additional Fees On Checkout (Free) plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘number’ parameter in all versions up to, and including, 1.4.7 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
The Additional Fees For WooCommerce Checkout plugin through version 1.4.7 contains a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in the browsers of site visitors, potentially stealing session data or performing actions on their behalf. The vulnerability requires user interaction—typically clicking a malicious link—and affects the broader site scope beyond the plugin itself.
What an attacker can do
Inject malicious scripts that run in visitors' browsers to steal data or perform unauthorized actions.
Potential impact on your site
