CVE-2026-54318
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
Home Assistant prior to version 2026.5.3 has a vulnerability in the LocationSensorManager component where the BroadcastReceiver is exported without required permissions. Any installed app, even without runtime permissions, can send a forged Google Play Services LocationResult that is trusted and forwarded to the Home Assistant server as the device's real location.
Risk Assessment
A local malicious app can bypass Android's 'Mock Location' gate and spoof the user's GPS position, enabling zone-based automations such as unlocking doors, disarming alarms, or opening garages.
Recommendation
Immediately update Home Assistant to version 2026.5.3 or later, which contains the fix for this vulnerability.

Original NVD description (English source)
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.
