Vulnerability from fkie_nvd - Published: 2026-07-03 00:16 - Updated: 2026-07-06 19:42
Severity
10.0 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L
Summary
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.
