Like, I hear all the time that you shouldn't open any ports on your networks fire wall for security reasons this and security reasons that. But what are the actual security implications/risks of forwarding a port for something like Jellyfin or a Minecraft server or something like that? Explain like im 16 (or something)

You’re allowing random people to access those services. Jellyfin almost definitely has a 0 day exploit so anyone who has access would potentially be able to use that on you. I would wager burning a 0 day on a random is probably not gonna be happening but also the odds of a random realizing they’ve been hacked is pretty low too so you never really know.
