What is CVE-2023-33193?

Emby Server, a popular home media server, may be susceptible to an authentication bypass due to improper validation of user account settings. The vulnerability arises when certain headers are spoofed, which can mislead the local/non-local network determination. This may allow unauthorized administrative access without proper password authentication. All publicly accessible Emby Server installations with default or weak settings are at risk, especially if account login configurations have not been reinforced. The issue has been addressed in Emby Server Beta version 4.8.31 and Emby Server version 4.7.12, emphasizing the necessity for regular updates to maintain security.
