CVE-2025-29757
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 · uneditedAn incorrect authorisation check in the the 'plant transfer' function of the Growatt cloud service allowed a malicous attacker with a valid account to transfer any plant into his/her account.
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 confidenceBroken access control vulnerability in Growatt cloud service's plant transfer function. The function fails to properly verify that the requesting user has authorization to transfer a specific plant, allowing any authenticated user to arbitrarily transfer ownership of any plant to their own account through the flawed authorization check.

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.
-
Confirm Growatt cloud service usageIdentify if your solar monitoring setup uses Growatt's cloud service (inverter data flows through server.growatt.com or similar Growatt cloud endpoints)Affected if Your system relies on Growatt's cloud platform for plant management and monitoring
-
Identify your registered plant IDsLog into your Growatt cloud account and navigate to the plant management section to list all plant IDs associated with your accountAffected if You have one or more plants registered in your Growatt cloud account
-
Test plant transfer function ownership validationAttempt a plant transfer API request to the transfer endpoint using a plant ID that does NOT belong to your account (but is valid on the platform), observing whether the system accepts the transfer without rejecting it for ownership violationAffected if The transfer request succeeds or returns a success status for a plant you do not own, indicating the ownership check is missing
-
Review account activity logs for plant transfersAccess your Growatt account audit logs or activity history and search for any plant transfer operations you did not initiate, particularly transfers TO or FROM your accountAffected if Plant transfer records exist that you did not authorize or that moved plants you did not previously own into your account without action on your part
-
Check for unexpected plant ownership changesCompare your current plant list against any known previous records or backups of your account to identify plants that were added or removed without your actionAffected if Your account shows plants you did not create or is missing plants you did not transfer away
Your environment is affected if you use Growatt's cloud service and the plant transfer function allows transferring plants you do not own, or if unauthorized plant transfers appear in your account activity.
Generated from the published advisory. Verify against your own configuration.
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 dataThe vendor must implement proper authorization validation in the plant transfer function to ensure users can only transfer plants they own or have been granted permission to manage. Until the vendor releases a patch, users should monitor account activity for unauthorized plant transfers.
