No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A Gardyn Azure IoT Hub connection string is downloaded over an insecure HTTP connection in Gardyn Home Kit firmware before master.619, Home Kit Mobile Application before 2.11.0, and Home Kit Cloud API before 2.12.2026 leaving the string vulnerable to interception and modification through a Man-in-the-Middle attack. This may result in the attacker capturing device credentials or taking control of vulnerable home kits.
