CVE-2025-36756
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 · uneditedA problem with missing authorization on SolaX Cloud platform allows taking over any SolaX solarpanel inverter of which the serial number is known.
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 confidenceMissing authorization in SolaX Cloud allows attackers to take control of any inverter by knowing its serial number, enabling unauthorized account takeover without proper authentication verification.

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 SolaX Cloud connectionLog into your SolaX Cloud account and navigate to the device/inverter list to verify your inverters are managed through this platformAffected if Your inverters are connected to SolaX Cloud and can be managed through the cloud portal
-
Review authorized inverters in your accountCheck the inverter list in your SolaX Cloud account for any unknown or unauthorized devices that may have been added using only a serial numberAffected if You see inverters in your account that you did not register or authorize
-
Examine account access logsLook for access logs or activity history in your SolaX Cloud account settings for entries showing access from unknown IP addresses or at unusual timesAffected if There are login or access events you cannot explain
-
Verify account security settingsCheck your SolaX Cloud account profile for available security options such as multi-factor authentication (MFA)Affected if MFA is not enabled or not available, meaning your account relies solely on password authentication
-
Confirm your inverter serial number is protectedReview whether your inverter serial number is displayed publicly or shared in forums, social media, or third-party monitoring servicesAffected if Your inverter serial number is publicly exposed and could be used by an attacker
You are affected if your inverters are connected to SolaX Cloud and unauthorized devices or access appear in your account, or if your account lacks additional authentication safeguards beyond password alone.
