Published

gonic versions before 0.22.0 fail to validate administrator privileges in the startScan endpoint, allowing any authenticated user to trigger media library rescans. Attackers can repeatedly call the startScan endpoint to force CPU and I/O-intensive filesystem operations, causing denial of service on multi-user instances.
