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 · unedited
An unauthenticated attacker can get users' emails by knowing usernames. A password reset email will be sent in response to this unsolicited request.

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 confidence

An unauthenticated attacker can trigger password reset emails by submitting valid usernames to the password reset function, enabling user enumeration and disclosure of associated email addresses through the reset email itself.

MitigationImplement rate limiting, CAPTCHA, or require email addresses instead of usernames for password reset requests to prevent enumeration and block automated abuse.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Growatt Cloud Portal version
    Check the portal interface for a version number, typically found in the About section, footer, or account settings. Alternatively, check API response headers or the login page source for version indicators.
    Affected if The displayed version is 3.6.0 or lower, indicating an unpatched installation.
  2. Examine the password reset form input
    Navigate to the password reset page on the Growatt Cloud Portal and inspect the input field placeholder text. Check whether it asks for 'Username' or 'Email address'.
    Affected if The field accepts usernames (e.g., placeholder says 'Enter your username') rather than only accepting email addresses.
  3. Test username enumeration vulnerability
    Submit a known-valid username to the password reset function using curl or browser developer tools. Observe whether a reset email is triggered versus an error message indicating the user does not exist.
    Affected if Submitting a valid username triggers a password reset email or returns a generic success message without confirming the username does not exist.
  4. Verify protection mechanisms
    Check the password reset endpoint for CAPTCHA challenges or rate limiting by attempting multiple reset requests. Inspect the page HTML for CAPTCHA widgets or check response headers for rate-limit headers.
    Affected if No CAPTCHA is present and no rate limiting is enforced on the password reset endpoint.

The environment is affected if the Growatt Cloud Portal version is 3.6.0 or lower and the password reset function accepts usernames instead of only email addresses without CAPTCHA or rate limiting protection.
