Hemmelig is a messing app with with client-side encryption and self-destructing messages. Prior to version 7.3.3, a Server-Side Request Forgery (SSRF) filter bypass vulnerability exists in the webhook URL validation of the Secret Requests feature. The application attempts to block internal/private IP addresses but can be bypassed using DNS rebinding or open redirect services. This allows an authenticated user to make the server initiate HTTP requests to internal network resources. Version 7.3.3 contains a patch for the issue.

Summary		(es) Hemmelig es una aplicación de mensajería con cifrado del lado del cliente y mensajes autodestructivos. Antes de la versión 7.3.3, existe una vulnerabilidad de omisión de filtro de falsificación de petición del lado del servidor (SSRF) en la validación de URL de webhook de la función de Solicitudes Secretas. La aplicación intenta bloquear direcciones IP internas/privadas, pero puede ser omitida usando reenlace de DNS o servicios de redirección abierta. Esto permite a un usuario autenticado hacer que el servidor inicie peticiones HTTP a recursos de red internos. La versión 7.3.3 contiene un parche para el problema.
