      "value": "RAGFlow before 0.26.3 contains a server-side request forgery vulnerability in the agent workflow \"Invoke\" component (agent/component/invoke.py). The component builds an outbound request URL from canvas configuration and runtime template variables and passes it to requests.get, requests.post, or requests.put without calling the shared assert_url_is_safe validator or pinning the resolved address, unlike the crawler, SearXNG, file-upload, and RSS fetch paths. A user who can create or trigger an agent can direct the server to fetch loopback, link-local, and RFC 1918 destinations, including cloud instance metadata endpoints and services co-located on the deployment network, and the response body is returned as the component output. Where an agent is configured to interpolate the chat query into the Invoke URL, the destination is chosen by whoever can send that query."

      "value": "RAGFlow anterior a la versión 0.26.3 contiene una vulnerabilidad de falsificación de petición del lado del servidor en el componente ’Invoke’ del flujo de trabajo del agente (agent/component/invoke.py). El componente construye una URL de petición saliente a partir de la configuración del lienzo y las variables de plantilla en tiempo de ejecución y la pasa a requests.get, requests.post o requests.put sin llamar al validador compartido assert_url_is_safe ni fijar la dirección resuelta, a diferencia de las rutas de obtención del rastreador, SearXNG, carga de archivos y RSS. Un usuario que puede crear o activar un agente puede dirigir al servidor para que obtenga destinos de loopback, link-local y RFC 1918, incluyendo puntos finales de metadatos de instancias en la nube y servicios co-ubicados en la red de despliegue, y el cuerpo de la respuesta se devuelve como la salida del componente. Cuando un agente está configurado para interpolar la consulta de chat en la URL de Invoke, el destino es elegido por quien pueda enviar esa consulta."
