CVE-2026-13768
Gardyn IoT Hub Use of Hard-coded Credentials
Description
Gardyn devices expose a privileged iothubowner key. Access to this key will allow a malicious user to invoke an IoTHub Registry Manager function which returns connection information for all Gardyn Home Kit and Studio devices. Access to this key also allows a malicious user to execute arbitrary commands on a specific connected device and may allow the malicious user to pivot to other devices on the user's network.

Solution
- Revoke and re-issue the privileged iothubowner key.
- Implement strict access controls for IoTHub functions.
- Disable or restrict remote command execution.
- Segment the user's network to limit pivot.
