Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)
CVE CVE-2024-8981
CVSS 7.1 (High)
Publicly Published September 30, 2024
Last Updated October 1, 2024
Researcher vgo0

Description

The Broken Link Checker plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg in /app/admin-notices/features/class-view.php without appropriate escaping on the URL in all versions up to, and including, 2.4.0. 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.
