    Affected if The version cannot be determined or is not clearly displayed
  3. Compare your version to the affected range
    Check if your installed version is 4.29.0 or any version lower (e.g., 4.28.0, 4.27.0, 3.x.x). The vulnerability affects all versions up to and including 4.29.0
    Affected if Your installed version is 4.29.0 or lower
  4. Confirm the plugin is active
    Log in to WordPress admin and navigate to Plugins > Installed Plugins, or check the wp_options table for the option_name 'active_plugins' to see if the plugin is enabled
