Versions 4.7.0 and below are vulnerable to an unauthenticated, full-read SSRF vulnerability. The ZITADEL Login UI (V2) treats the x-zitadel-forward-host header as a trusted fallback for all deployments, including self-hosted instances. This allows an unauthenticated attacker to force the server to make HTTP requests to arbitrary domains, such as internal addresses, and read the responses, enabling data exfiltration and bypassing network-segmentation controls. This issue is fixed in version 4.7.1."},{"lang":"es","value":"ZITADEL es una herramienta de infraestructura de identidad de código abierto. Las versiones 4.7.0 e inferiores son vulnerables a una vulnerabilidad SSRF no autenticada, de lectura completa. La interfaz de usuario de inicio de sesión de ZITADEL (V2) trata el encabezado x-zitadel-forward-host como un respaldo de confianza para todos los despliegues, incluidas las instancias autoalojadas. Esto permite a un atacante no autenticado forzar al servidor a realizar solicitudes HTTP a dominios arbitrarios, como direcciones internas, y leer las respuestas, lo que permite la exfiltración de datos y eludir los controles de segmentación de red.
