Prior to version 2.0.13, fallbackToFrontend in the dashboard's NoRoute handler treats any URL whose raw string starts with /dashboard as an admin-frontend asset request. The check uses strings.HasPrefix, not a path-segment match, so the input /dashboard../data/config.yaml is accepted; strings.TrimPrefix leaves ../data/config.yaml; and path.Join(\"admin-dist\", \"../data/config.yaml\") normalizes to data/config.yaml — which os.Stat finds and http.ServeFile returns. No authentication required.
