VNC authentication is an utter joke. It can be trivially brute forced
so exposing it on a public IP address is not a good idea, hence the
default is, though even that's not ideal because it is still
exposed to local users. Ultimately VNC needs to have  SSL/TLS support
integrated into it to allow secure access over public network, which
is something I'm working on for QEMU...
