CVE-2026-54317

CVE-2026-54317 · Home Assistant: Konnected alarm-panel switch state and zone topology disclosed to unauthenticated actors on the LAN

This page contains facts from public vulnerability sources. Check the original advisory before updating.

This page shows selected source facts. See the linked advisories for the complete description and affected versions.

Home Assistant is open source home automation software that puts local control and privacy first. Prior to 2026.6.0, the Konnected integration registers an HTTP endpoint, KonnectedView (homeassistant/components/konnected/__init__.py), that is marked as not requiring authentication (requires_auth = False). A comment next to that line says auth is instead handled "via the access token from configuration." That promise is only half true. Write requests (POST and PUT) are handled by update_sensor(), which does check the request's Authorization: Bearer <token> header against the integration's stored access tokens (using hmac.compare_digest). Read requests (GET) are handled by a separate get() method that has no authentication check at all. This vulnerability is fixed in 2026.6.0.
