CSRF in Wpkuf Wp Js Detect
CVE-2026-9731
The Wp Js Detect plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.9. This is due to missing or incorrect nonce validation on the plugin_settings function. This makes it possible for unauthenticated attackers to update the plugin's notification text and CSS settings (wp_non_js_notification_text and wp_non_js_notification_css), injecting arbitrary content that is echoed unescaped on the frontend via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
