Auth bypass in Dannymcc Bluehood

CVE-2026-49994

Bluehood monitors local bluetooth activity. Prior to version 0.7.1, when auth_enabled is set in Bluehood, only the HTML page handlers enforced session validation. The /api/* handlers (settings, devices, groups, per-device endpoints including /api/device/{mac}/notes) called no auth check at all. A network attacker reachable on the dashboard port could read Bluetooth tracking data and modify application state — including the heartbeat URL, prune retention, device groups, and per-device notes — without a session cookie. This issue has been patched in version 0.7.1.
