CVE-2025-27112: Navidrome allows an authentication bypass in Subsonic API with non-existent username
(updated )
In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error.
