CVE-2026-4267

The Query Monitor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the '$_SERVER['REQUEST_URI']' parameter in all versions up to, and including, 3.20.3. This is due to insufficient input sanitization and output escaping. An unauthenticated attacker could inject arbitrary web scripts if they can trick a user into performing an action such as clicking on a link.
