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. Confirm Funnel Builder for WooCommerce Checkout is installed
    Navigate to WordPress Admin > Plugins and locate 'Funnel Builder for WooCommerce Checkout' in the installed plugins list, or check the plugin header file (usually in wp-content/plugins/funnel-builder-for-woocommerce-checkout or similar path) for the Version header
    Affected if The plugin is installed and the version is earlier than 3.15.0.3
  2. Locate the plugin version number
    In WordPress Admin > Plugins, click on the plugin to view details and read the Version field, or open the main plugin PHP file and search for 'Version:' in the plugin header comment
    Affected if The displayed version is below 3.15.0.3 (for example, 3.14.x, 3.13.x, etc.)
  3. Inspect the External Scripts global setting
    Go to the plugin settings area in WordPress Admin (typically under WooCommerce > Funnel Builder or a similar menu path) and locate the External Scripts or Custom Scripts field. View the page source or inspect the input to see if any script tags are present in the value
    Affected if The External Scripts setting contains script tags with unfamiliar or suspicious URLs, especially if they were not added by your team
  4. Check WordPress options database for injected scripts
    Use a database tool or WordPress plugin to query the wp_options table for any option_name containing 'external_script', 'custom_script', or 'funnel' related settings. Examine the option_value for any script tags, especially those using eval(), document.write(), or external domains
    Affected if Any option value contains JavaScript that was not intentionally configured by administrators

Your environment is affected if the Funnel Builder for WooCommerce Checkout plugin is installed with a version lower than 3.15.0.3, or if the External Scripts setting contains unauthorized JavaScript code.
