I've recently learned of an Emby exploit for local servers that are configured to be accessible via the Internet.
Please check out the link for fixes until a patch is released!

Combined with the "Proxy Header Vulnerability", which was recently fixed in the beta channel, this allowed an attacker to gain administrative access on such systems. Eventually, this allowed the attackers to install a custom plugin of their own, which establishes a backdoor in the running process of Emby Server.
