CVE-2026-6405
Anomify AI <= 0.3.6 - Cross-Site Request Forgery
Description

The Anomify AI – Anomaly Detection and Alerting plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) leading to Stored Cross-Site Scripting (XSS) in versions up to and including 0.3.6. This is due to missing nonce verification on the settings page handler and insufficient output escaping in the admin_options.php template. The settings form includes no wp_nonce_field() and the handler performs no check_admin_referer() check, meaning any cross-origin POST can modify plugin settings. The API key field is sanitized only with sanitize_text_field(), which strips HTML tags but does not encode double-quote characters; the value is then rendered into an HTML attribute via bare echo without esc_attr(), allowing a double-quote attribute-escape payload to survive both sanitization and storage. This makes it possible for unauthenticated attackers to inject arbitrary web scripts by tricking a logged-in administrator into visiting a malicious page that submits a forged request, storing the payload in the database and causing it to execute in the administrator's browser whenever the plugin settings page is visited.

    Added Translation Title: plugin de WordPress Anomify AI, Description: El plugin Anomify AI - Detección de Anomalías y Alertas para WordPress es vulnerable a Falsificación de Petición en Sitios Cruzados (CSRF) lo que lleva a Cross-Site Scripting Almacenado (XSS) en versiones hasta la 0.3.6 inclusive. Esto se debe a la falta de verificación de nonce en el gestor de la página de configuración y a un escape de salida insuficiente en la plantilla admin_options.php. El formulario de configuración no incluye wp_nonce_field() y el gestor no realiza ninguna comprobación check_admin_referer(), lo que significa que cualquier POST de origen cruzado puede modificar la configuración del plugin. El campo de clave API se sanitiza solo con sanitize_text_field(), que elimina las etiquetas HTML pero no codifica los caracteres de comillas dobles; el valor se renderiza luego en un atributo HTML mediante un echo simple sin esc_attr(), lo que permite que una carga útil de escape de atributo de comillas dobles sobreviva tanto a la sanitización como al almacenamiento. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios engañando a un administrador que ha iniciado sesión para que visite una página maliciosa que envía una petición falsificada, almacenando la carga útil en la base de datos y haciendo que se ejecute en el navegador del administrador cada vez que se visita la página de configuración del plugin.
