CVE-2026-54318
Home Assistant: Exported BroadcastReceiver allows local apps to spoof device location
Description
Home Assistant is open source home automation software that puts local control and privacy first. Prior to 2026.5.3, the LocationSensorManager BroadcastReceiver is exported with no permission. Any installed app, with zero runtime permissions, can broadcast a forged Google Play Services LocationResult directly to it; the receiver trusts the extra and forwards it to the user's Home Assistant server as the device's real location. This bypasses Android's developer-mode "Mock Location" gate and allows a local malicious app to drive zone-based automations (unlock door / disarm alarm / open garage) by faking the user's GPS position. This vulnerability is fixed in 2026.5.3.

Action Type Old Value New Value Added Translation Title: core de home-assistant, Description: Home Assistant es un software de automatización del hogar de código abierto que prioriza el control local y la privacidad. Antes de la versión 2026.5.3, el BroadcastReceiver LocationSensorManager se exporta sin ningún permiso. Cualquier aplicación instalada, sin permisos de tiempo de ejecución, puede transmitir un LocationResult falsificado de Google Play Services directamente a este; el receptor confía en el extra y lo reenvía al servidor de Home Assistant del usuario como la ubicación real del dispositivo. Esto elude la puerta de ’Ubicación simulada’ del modo de desarrollador de Android y permite que una aplicación maliciosa local impulse automatizaciones basadas en zonas (desbloquear puerta / desarmar alarma / abrir garaje) al falsificar la posición GPS del usuario. Esta vulnerabilidad se corrige en la versión 2026.5.3. -
