An attacker could gain administrative access, meaning they can view all user accounts—even those without passwords—and manipulate settings to their liking. Imagine someone walking into your home, browsing your personal collection, and changing everything without you lifting a finger!
Think of your Emby Server as a private movie theater where only VIPs should enter. If someone can fake their way in by misrepresenting their ticket, they could easily browse through your entire film collection without you ever knowing! By spoofing specific headers meant for reverse proxy interactions, unauthorized users can bypass login protections and gain administrative privileges on the Emby Server, which is particularly dangerous for publicly accessible installations with relaxed security settings.
