CVE-2025-31654
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 attacker can get information about the groups of the smart home devices for arbitrary users (i.e., "rooms").
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 · moderate confidenceThis is an Insecure Direct Object Reference (IDOR) vulnerability in a smart home application that allows attackers to enumerate device group information (rooms) for arbitrary users by manipulating user identifiers in API requests. The lack of proper authorization checks on endpoints exposing user-specific data enables unauthorized access to sensitive grouping information.

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 Growatt Cloud Portal versionLocate the installed version of the Growatt Cloud Portal application through the application UI (typically found in About/Settings section) or by checking the software build information. Compare this version against the affected range: <= 3.6.0Affected if The installed version is 3.6.0 or lower
-
Identify API endpoints exposing device group dataReview application documentation or use web traffic analysis tools to capture API requests that return device group or room information. Look for endpoints that accept user identifiers as parameters.Affected if API endpoints exist that return user-specific device group (room) data and accept user IDs as request parameters
-
Test authorization on device group endpointsCapture an authenticated API request that returns your own device group/room information. Modify the user identifier parameter in the request to reference a different user ID, then observe whether the response returns that user's device group data without proper authorization errors.Affected if Manipulating user identifiers in API requests returns device group data for users other than the authenticated user, indicating missing authorization checks
You are affected if your Growatt Cloud Portal version is 3.6.0 or lower AND API endpoints expose device group information that can be accessed by manipulating user identifiers to view other users' room data.

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 dataImplement consistent authorization validation to ensure users can only access their own device group data, and audit all endpoints that return user-specific information for similar access control issues.
