CVE-2024-6020 – Sign-up Sheets < 2.2.13 - Reflected XSS

https://notcve.org/view.php?id=CVE-2024-6020

The Sign-up Sheets WordPress plugin before 2.2.13 does not escape some generated URLs, as well as the $_SERVER['REQUEST_URI'] parameter before outputting them back in attributes, which could lead to Reflected Cross-Site Scripting. The Sign-up Sheets plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of $_SERVER['REQUEST_URI'] without appropriate escaping on the URL in all versions up to, and including, 2.2.12. 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. • https://wpscan.com/vulnerability/f3526320-3abd-4ddb-8f73-778741bd9c48 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
