CVE-2025-1242Network attack vector

IoT fleet control via exposed administrative credentials

Published Feb 25, 2026 · Updated Feb 25, 2026

Hard-coded credentials in Gardyn Home Kit components before their fixed releases allow remote attackers to administer the Gardyn IoT Hub. An unauthenticated provisioning API returned the iothubowner connection string, while the React Native bundle and firmware files under /usr/local/etc/gardyn/ embedded the same secret. No account or user interaction is required; possession of the shared key permits device enumeration, direct-method invocation, device-twin changes, and device registration changes.
