CVE-2026-72598

A server-side request forgery vulnerability in Apioo Fusio 8.8.3 allows authenticated consumer-role users to make the server issue HTTP requests to internal network addresses by registering a webhook URL pointing to an internal host. The webhook registration endpoint validates URL syntax via FILTER_VALIDATE_URL but applies no IP or host denylist. When the registered event fires, the server issues an HTTP POST to the attacker-supplied internal URL.

Summary		(es) Una vulnerabilidad de falsificación de petición del lado del servidor en Apioo Fusio 8.8.3 permite a usuarios autenticados con rol de consumidor hacer que el servidor emita peticiones HTTP a direcciones de red internas al registrar una URL de webhook que apunte a un host interno. El endpoint de registro de webhook valida la sintaxis de la URL a través de FILTER_VALIDATE_URL pero no aplica ninguna lista de denegación de IP o host. Cuando el evento registrado se dispara, el servidor emite un POST HTTP a la URL interna proporcionada por el atacante.
