Is docker running on 0.0.0.0 posing a threat?

Hi,

(1) I just hear about this serious old vulnerability and was wondering if all my docker container, that are running on 0.0.0.0 would pose a threat to the system they are running on.

(2) I further read that all major browsers are working on a solution that would simply be to block this address. Would then my container stop to work?

(3) My setup usually is, that the app inside my docker container casts on 0.0.0.0 which is forwarded by the container, that itself runs on 0.0.0.0 which is then reachable on my machine’s browser. Is there a way to change this to a different IP?

I’m pretty sure I’m mixing things up somewhere and that I do not fully understand what I’m writing but perhaps someone could clarify this.
