CVE-2024-6517 – Contact Form 7 Math Captcha <= 2.0.1 - Reflected XSS

https://notcve.org/view.php?id=CVE-2024-6517

The Contact Form 7 Math Captcha WordPress plugin through 2.0.1 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users. The Contact Form 7 Math Captcha plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tagname' parameter in all versions up to, and including, 2.0.1 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. • https://wpscan.com/vulnerability/d04bab9c-7cb4-4d21-b70b-a4a7fabc3c20 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
