Yup. Technically, just one external reference outside of the sandbox environment from within the sandbox environment ("software stargate portal address to alternate environment" / one evaluated part of the s-expression using a system() reference).

Running software is insecure the moment the electrical switch is on / start checking out shrodingers box. Although, reverse shrodingers cat might be more accurate. aka can escape the box if someone peaks from outside the box.
