Sure it will be much harder.  But even if an exploit that works on all
Forth systems would be impossible, the problem of possible attacks
against a specific program running on a specific system still exists,
and we should be thinking about supporting the programmers in
defending agains that, at least if we don't want to limit Forth to
application areas like 1960s TVs as suggested by Albert van der Horst.
