CVE-2026-7414
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 · uneditedYarbo firmware v2.3.9 contains hardcoded administrative credentials embedded in the firmware image. These credentials are identical across all devices running this firmware and cannot be changed or removed by end users, enabling trivial unauthorized access to device management interfaces by anyone who knows them.
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 confidenceYarbo firmware v2.3.9 contains hardcoded administrative credentials embedded directly in the firmware image. These credentials are identical across all devices running this firmware version and cannot be modified or removed by end users, providing trivial unauthorized access to device management interfaces.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Yarbo device firmware versionAccess the device management interface or check the device settings menu to locate the firmware version information. This is typically found under Settings > Device Info or a similar section of the Yarbo mobile app or web interface.Affected if The displayed firmware version is exactly 2.3.9 for either the standard Yarbo Lawn Mower or Yarbo Lawn Mower Pro model.
-
Confirm device model variantVerify whether the device is a standard Yarbo Lawn Mower or a Yarbo Lawn Mower Pro variant by checking the product label or device information screen.Affected if The device is either the standard Yarbo Lawn Mower or the Yarbo Lawn Mower Pro, and the firmware version shown is 2.3.9.
-
Check for exposed management interfacesDetermine if the device administrative interface is accessible from external networks by reviewing network firewall rules, port forwarding configurations, or by attempting to reach the device on common management ports from outside the local network.Affected if The device management interface is reachable from untrusted networks and the firmware version is 2.3.9.
-
Review access logs for unauthorized accessExamine device logs or network security logs for login attempts using default or administrative credentials that you did not configure, particularly from external IP addresses.Affected if Unexplained administrative logins appear in the logs and the device runs firmware version 2.3.9.
You are affected if your Yarbo Lawn Mower or Yarbo Lawn Mower Pro device is running firmware version exactly 2.3.9 and has its management interface accessible from the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediate network segmentation to isolate affected devices from untrusted networks; coordinate with Yarbo vendor for firmware update containing removable/changing credentials; monitor for unauthorized access using the known hardcoded credentials.
