Description: Gameyfin before 2.6.2 contains a missing authorization vulnerability that allows unauthenticated attackers to bypass login-required mode by calling Hilla endpoints annotated with @AnonymousAllowed. Attackers can POST to synchronous endpoint methods such as GameEndpoint.sync, which LiveSubscriptionSecurity never checks, to retrieve game catalog metadata, libraries, platforms, plugins and game requests.
