CVE-2025-63388

A Cross-Origin Resource Sharing (CORS) misconfiguration vulnerability exists in Dify v1.9.1 in the /console/api/system-features endpoint. The endpoint implements an overly permissive CORS policy that reflects arbitrary Origin headers and sets Access-Control-Allow-Credentials: true, allowing any external domain to make authenticated cross-origin requests. NOTE: the Supplier disputes this, providing the rationale of "sending requests with credentials does not provide any additional access compared to unauthenticated requests."

Summary		(es) Una vulnerabilidad de configuración incorrecta de Cross-Origin Resource Sharing (CORS) existe en Dify v1.9.1 en el endpoint /console/API/system-features. El endpoint implementa una política CORS excesivamente permisiva que refleja encabezados Origin arbitrarios y establece Access-Control-Allow-Credentials: true, permitiendo a cualquier dominio externo realizar solicitudes de origen cruzado autenticadas. NOTA: el Proveedor lo disputa, proporcionando la justificación de 'enviar solicitudes con credenciales no proporciona ningún acceso adicional en comparación con las solicitudes no autenticadas.'
