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 plugin installation
    Navigate to WordPress admin > Plugins and locate 'Flintop Free Gifts for WooCommerce' or search for 'flintop' in the plugins list. Verify the plugin is active.
    Affected if The plugin is installed and active in WordPress.
  2. Identify installed version
    In the Plugins list, click on the plugin name or view details to find the version number displayed (typically listed below the plugin name). Compare this version to 13.1.0.
    Affected if The installed version is 13.1.0 or lower.
  3. Check for gift configuration data
    Access the plugin settings: typically found under WooCommerce > Free Gifts or a similar menu item. Review any existing gift rules, product selections, or custom text fields where user-supplied data may be stored.
    Affected if Gift rules or configurations exist in the plugin, indicating the feature where unsanitized input could be stored is in use.
  4. Inspect stored gift data in database
    Access the WordPress database via phpMyAdmin or wp-cli. Query the wp_postmeta table for postmeta_key fields related to the plugin (common patterns include 'flintop_free_gift', 'free_gift', or similar prefixes). Examine the meta_value columns for any raw HTML or script tags.
    Affected if Stored meta data contains unescaped HTML or JavaScript characters indicating a lack of output encoding.

You are affected if the Flintop Free Gifts for WooCommerce plugin is active at version 13.1.0 or lower and gift configuration features have been used, as this creates the conditions for stored XSS to execute.
