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. Check WD My Cloud web interface version
    Log into the WD My Cloud web interface (typically at mycloud.com or the device's local IP address). Navigate to Settings > About or Settings > System to find the Web Version or Firmware Version information.
    Affected if The displayed Web Version is less than 2.2.0-134 (for example, 2.2.0-100 or earlier)
  2. Verify version via device firmware
    Access the device's administrative panel and locate the firmware version information, which typically includes the web interface version.
    Affected if The firmware/web version shown is below 2.2.0-134
  3. Check for XSS exposure in web parameters
    If you have access to the device's web interface, examine URL parameters and form inputs in the mycloud.com interface for unvalidated input reflection.
    Affected if User-supplied input in web requests is reflected back without proper encoding or sanitization, indicating the XSS vulnerability is present

A user is affected if their WD My Cloud device runs a web interface version earlier than 2.2.0-134, as confirmed by checking the version displayed in the device settings or about page.
