CVE-2026-59207

n8n is an open source workflow automation platform. Prior to 2.27.4 and 2.28.1, the AI Agents feature did not enforce the Allowed HTTP Request Domains restriction configured on credentials when an MCP tool was pointed at an arbitrary URL, allowing a member-level user with use-only access to a shared credential to send its secret to an external server they control. This issue is fixed in versions 2.27.4 and 2.28.1.

Summary		(es) n8n es una plataforma de automatización de flujos de trabajo de código abierto. Antes de las versiones 2.27.4 y 2.28.1, la función de Agentes de IA no aplicaba la restricción de Dominios HTTP de Solicitud Permitidos configurada en las credenciales cuando una herramienta MCP apuntaba a una URL arbitraria, permitiendo a un usuario de nivel miembro con acceso de solo uso a una credencial compartida enviar su secreto a un servidor externo que controlaba. Este problema está solucionado en las versiones 2.27.4 y 2.28.1.
