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. Verify Samsung Cloud app is installed
    Go to Settings > Apps on the Android device and search for Samsung Cloud, or check the app drawer for the Samsung Cloud icon
    Affected if Samsung Cloud app is present on the device
  2. Locate the installed version of Samsung Cloud
    In Settings > Apps > Samsung Cloud, tap on App info or scroll to view the Version number displayed under the app name
    Affected if Unable to determine the version number from app settings
  3. Compare your version against the affected range
    Note the version number shown (for example, 5.2.00.1 or similar) and compare it numerically to 5.3.00.4 - any version lower than 5.3.00.4 is affected
    Affected if Installed version is less than 5.3.00.4 (for example, 5.2.00.x, 5.1.x.x, etc.)

You are affected if Samsung Cloud is installed and its version number is lower than 5.3.00.4
