      "value": "FastGPT is an AI Agent building platform. Prior to version 4.14.17, FastGPT had an inconsistent SSRF protection gap in MCP tool URL handling. The direct MCP preview/run endpoints already rejected internal/private network URLs, but the MCP tool create/update endpoints could still save an internal MCP server URL. That stored URL could later be used by workflow execution without revalidating the destination. An authenticated user with permission to create or manage MCP toolsets could store an internal endpoint such as http://localhost:3000/mcp and later cause the FastGPT backend workflow runner to connect to that internal destination. This issue has been patched in version 4.14.17."

      "value": "FastGPT es una plataforma de creación de agentes de IA. Antes de la versión 4.14.17, FastGPT tenía una brecha de protección SSRF inconsistente en el manejo de URL de herramientas MCP. Los puntos finales directos de vista previa/ejecución de MCP ya rechazaban las URL de red interna/privada, pero los puntos finales de creación/actualización de herramientas MCP aún podían guardar una URL de servidor MCP interna. Esa URL almacenada podría ser utilizada más tarde por la ejecución del flujo de trabajo sin revalidar el destino. Un usuario autenticado con permiso para crear o administrar conjuntos de herramientas MCP podría almacenar un punto final interno como http://localhost:3000/mcp y más tarde hacer que el ejecutor de flujos de trabajo de backend de FastGPT se conectara a ese destino interno. Este problema ha sido parcheado en la versión 4.14.17."
