Shell commands executed by the tool run without any filesystem or network restrictions, allowing unrestricted access to the host filesystem and network from within the computer-use agent process. This issue only affects deployments where the @n8n/computer-use package is explicitly installed and running; standard n8n installations are not affected."

Los comandos de shell ejecutados por la herramienta se ejecutan sin restricciones de sistema de archivos o de red, permitiendo acceso sin restricciones al sistema de archivos y a la red del host desde dentro del proceso del agente de computer-use. Este problema solo afecta a las implementaciones donde el paquete @n8n/computer-use está explícitamente instalado y en ejecución; las instalaciones estándar de n8n no se ven afectadas."
