      "value": "FastGPT is a knowledge-based AI application platform. Prior to 4.15.0-beta5, FastGPT's shared SSRF guard validates only the initial request URL before handing the request to axios, and axios follows redirects by default. An authenticated workflow user can configure an HTTP request node to call an attacker-controlled public URL that redirects to cloud metadata, loopback, or internal services that the guard would block on direct request, and the HTTP node returns the response body to the workflow caller. This issue is fixed in version 4.15.0-beta5."

      "value": "FastGPT es una plataforma de aplicación de IA basada en conocimiento. Antes de la versión 4.15.0-beta5, el guardián SSRF compartido de FastGPT valida solo la URL de la solicitud inicial antes de entregar la solicitud a axios, y axios sigue las redirecciones por defecto. Un usuario de flujo de trabajo autenticado puede configurar un nodo de solicitud HTTP para llamar a una URL pública controlada por el atacante que redirige a metadatos de la nube, loopback o servicios internos que el guardián bloquearía en una solicitud directa, y el nodo HTTP devuelve el cuerpo de la respuesta al llamador del flujo de trabajo. Este problema está solucionado en la versión 4.15.0-beta5."
