I don't know any way you could forward a port from a remote host to
anywhere without authenticating on said remote host.
I'm not quite sure why you consider the existance of an account to be a
security hole ? you could configure an account that won't allow an
interactive login (shell set to /bin/false), and JUST do port
forwarding, using -N on the ssh command.
