What's the security situation when opening a jellyfin server up for casting? (feddit.nu)

when reading through the jellyfin with chromecast guide i realized that it would probably be less effort to just let the casting api be public, with the added bonus that i could then cast my library to any device that supports it. but that seems like it would paint a giant target on the server.

what's the recommended way of doing stuff like this? ideally i want to be able to go to someone's house and just play some of my media on their tv.

not that any of this is doable in the near future, since i'm behind cgnat and won't get my colocated bounce server up until spring.

Aren't zero day very specific? Or maybe it's become a very generic term.

Anyway, I am under the impression that either it's suddenly very simple to hack into EVERYONE because someone zero dayed the wireguard protocol and there a major flow in it, it's a shitshow, for all, for some, just me or nobody, whatever. Or it's a very targeted attack on me personaly, and that's a whole other story and the means to protect my pictures of my cats and my cool public domain movies collection are different (think social engineering). Also port 22 being bombarded by brute force attempts so don't choose a password that's 6 letters thanks.

I KNOW I am missing many things, but still, I don't get it.
