      "value": "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."

      "value": "Home Assistant es un software de automatización del hogar de código abierto que prioriza el control local y la privacidad. Antes de la versión 2026.6.0, la integración de Konnected registra un punto final HTTP, KonnectedView (homeassistant/components/konnected/__init__.py), que está marcado como que no requiere autenticación (requires_auth = False). Un comentario junto a esa línea dice que la autenticación se maneja en su lugar ’a través del token de acceso de la configuración’. Esa promesa es solo parcialmente cierta. Las solicitudes de escritura (POST y PUT) son manejadas por update_sensor(), que sí verifica el encabezado Authorization: Bearer [token] de la solicitud contra los tokens de acceso almacenados de la integración (usando hmac.compare_digest). Las solicitudes de lectura (GET) son manejadas por un método get() separado que no tiene ninguna verificación de autenticación en absoluto. Esta vulnerabilidad está corregida en la versión 2026.6.0."
