CVE-2026-13768Public exploitNetwork attack vector

Fleet-wide device control via privileged shared key

Published Jul 2, 2026 · Updated Jul 2, 2026

Hard-coded credentials in Gardyn Cloud API and device firmware allow remote attackers to enumerate devices and execute commands. A privileged iothubowner shared-access key grants RegistryRead and ServiceInvoke permissions across the fleet instead of limiting each device to a unique identity. Possession of the key is required; it reveals connection data for all Home and Studio devices and enables direct-method command execution on a selected online device, creating a foothold on its local network.
