Vulnerabilidad · Publicado 07/08/2026 · Actualizado 08/08/2026
Home Assistant versiones anteriores a 2026.5.0 presentan una vulnerabilidad alta en la aplicación iOS Companion que permite a aplicaciones no confiables ejecutar acciones mediante enlaces NFC o QR sin validación ni confirmación del usuario. Un atacante podría interceptar o redirigir estas acciones para comprometer dispositivos domóticos, sistemas de control industrial o infraestructura conectada en empresas LATAM. El riesgo es elevado en entornos con múltiples dispositivos IoT altas.
Home Assistant is open source home automation software focused on local control and privacy. Prior to 2026.5.0, the iOS Companion app treats tag links (NFC or QR) delivered through an OS-level routing mechanism such as iOS universal links as if they were physically scanned, without validating the calling app or prompting the user. As a result, any untrusted app on the device can forward an arbitrary tag to Home Assistant, causing it to execute the associated automation as though a legitimate user had scanned an authorized tag. This allows silent, unattended automation execution by untrusted local callers. This issue has been fixed in version 2026.5.0.
