tunneling - Are there any security flaws when exposing local sites via Ngrok? -

i addicted exposing local sites via ngrok remote testing , love it! might end making pc becoming vulnerable internet attacks.

although read ngrok – tool... , tunnelling... , both state ngrok supports secure tunnels localhost

are there other things must worry regards security whilst using tool?

since ngrok exposes 80 , 443 you're vulnerable underlying app server being exposed (modulo bugs in ngrok, sake of argument assume there none).
