CVE-2024-8981

CVSS v3.1

7.1

High

VectorAV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
Name of the Vulnerable Software and Affected Versions: Broken Link Checker plugin for WordPress versions up to, and including, 2.4.0
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. 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.
Recommendations: For versions up to, and including, 2.4.0, update to a version higher than 2.4.0 to resolve the issue. As a temporary workaround, consider restricting access to the /app/admin-notices/features/class-view.php file until a patch is available. Avoid using the add query arg function in the affected API endpoint until the issue is resolved.
