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.
