CVE-2025-31950
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 unauthenticated attacker can obtain EV charger energy consumption information of other users.
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 confidenceThe vulnerability allows unauthenticated attackers to access energy consumption data from EV chargers belonging to other users, indicating a broken access control vulnerability where the system fails to properly validate user authorization before disclosing sensitive charging session data.

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 Portal usageIdentify if your organization uses the Growatt Cloud Portal for EV charger management. Check your deployed services, subscriptions, or documentation for references to Growatt.Affected if You do not use Growatt Cloud Portal, then this CVE does not apply to your environment.
-
Check installed versionLog into the Growatt Cloud Portal interface and navigate to the account settings, system information, or about section to locate the software version. Alternatively, inspect API responses from the portal for version information in headers or response bodies.Affected if The version displayed is 3.6.0 or lower, indicating you are using an affected version.
-
Verify API endpoint access controlsExamine the API endpoints used by the EV charging functionality. Attempt to access charging session data endpoints with valid authentication tokens from one user account, then verify whether the system properly validates ownership before returning data.Affected if The API returns data from other users' charging sessions without proper ownership validation, indicating the broken access control vulnerability is present.
-
Review authentication requirementsCheck whether all EV charging data API endpoints require valid authentication. Attempt to access these endpoints without providing any authentication credentials.Affected if The system returns sensitive charging data without requiring authentication, confirming the unauthenticated access vulnerability.
You are affected if your environment runs Growatt Cloud Portal version 3.6.0 or lower and the EV charging API endpoints expose other users' data without proper authorization validation.

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 proper authentication and authorization checks to ensure users can only access their own charging data, and validate all API endpoints to prevent IDOR-based information disclosure.
