Description
The Smart Custom 404 Error Page plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via $_SERVER['REQUEST_URI'] in all versions up to, and including, 11.4.7 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.
Affected configurations
• nerdpress smart custom 404 error page (< 11.4.8)
