Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Gardyn Home Kit firmware before master.619, Home Kit Mobile Application before 2.11.0, and Home Kit Cloud API before 2.12.2026 allow command injection through vulnerable methods that do not sanitize input before passing content to the operating system for execution. The vulnerability may allow an attacker to execute arbitrary operating system commands on a target Home Kit.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OS command injection vulnerability in Gardyn Home Kit allows attackers to execute arbitrary operating system commands through unsanitized input being passed to system calls. Affected components include firmware before master.619, mobile application before 2.11.0, and cloud API before 2.12.2026.

MitigationUpdate to fixed versions (firmware master.619+, mobile app 2.11.0+, cloud API 2.12.2026+) and implement parameterized command execution with strict input validation to prevent injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Gardyn firmware version
    Access the Gardyn device settings or admin interface to locate the firmware version number. This is typically found in the device information or system settings section of the mobile application or web portal.
    Affected if Firmware version is earlier than master.619 (e.g., master.600, master.610, etc.)
  2. Identify Gardyn mobile application version
    Check the installed app version on your mobile device. On iOS, go to Settings > Apps > Gardyn > Version. On Android, go to Settings > Apps > Gardyn > App info. Alternatively, check the version displayed within the app's About or Settings section.
    Affected if Mobile application version is earlier than 2.11.0 (e.g., 2.9.0, 2.10.0, etc.)
  3. Identify Gardyn cloud API version
    Check the API version by reviewing the API endpoint responses, checking the service documentation, or accessing the cloud administration panel. The version may be visible in response headers or API documentation.
    Affected if Cloud API version is earlier than 2.12.2026 (e.g., 2.10.2025, 2.11.2025, etc.)
  4. Determine if remote/network access is enabled
    Examine the Gardyn device and application network configuration settings. Check if remote access features, cloud connectivity, or external API interfaces are enabled and accessible over the network.
    Affected if Remote or network-based access to the Gardyn system is enabled, allowing external attackers to reach the command injection entry point

You are affected if any of the three components (firmware before master.619, mobile app before 2.11.0, or cloud API before 2.12.2026) are in use AND the system has network/external access that could allow an attacker to supply malicious input to the affected command execution feature.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to fixed versions (firmware master.619+, mobile app 2.11.0+, cloud API 2.12.2026+) and implement parameterized command execution with strict input validation to prevent injection.

Recommended fix High confidence

Gardyn Home Kit firmware master.619 or later; Home Kit Mobile Application 2.11.0 or later; Home Kit Cloud API 2.12.2026 or later

  1. Identify the Gardyn Home Kit device and determine the current firmware version installed
  2. Check if firmware version is below master.619; if so, update to firmware master.619 or later from the vendor's official firmware distribution
  3. Identify the Home Kit Mobile Application version currently installed on mobile devices
  4. Update the Home Kit Mobile Application to version 2.11.0 or later via the official app store (Apple App Store or Google Play Store)
  5. Identify the Home Kit Cloud API version currently deployed
  6. Update the Home Kit Cloud API to version 2.12.2026 or later from the vendor's official release
  7. After updating all components, verify the installed versions match the fixed releases (firmware master.619+, app 2.11.0+, API 2.12.2026+)
  8. Test the system to confirm normal operation post-update
Caveat Ensure compatibility of other integrated systems with the new firmware, mobile app, and API versions before deploying in production
