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. Locate the Smart Coupons plugin installation
    Check the WordPress plugins directory at wp-content/plugins/ for a folder named 'smart-coupons-for-woocommerce' or similar WebToffee coupon plugin folder. If using a managed host, access via FTP or file manager.
    Affected if The plugin folder exists in the WordPress plugins directory
  2. Identify the installed plugin version
    Open the main plugin PHP file (usually the first PHP file in the plugin folder) and locate the 'Version' header in the plugin comment block at the top. Alternatively, log into the WordPress admin dashboard, go to Plugins > Installed Plugins, and find the Smart Coupons entry to see its current version number.
    Affected if The version number displayed is lower than 2.3.0 (for example: 2.2.9, 2.2.8, 2.0.x, etc.)
  3. Verify the plugin is active on the site
    In the WordPress admin under Plugins > Installed Plugins, confirm the Smart Coupons for WooCommerce plugin shows as 'Active'. A plugin must be active for the authorization bypass to be exploitable.
    Affected if The plugin is installed AND active AND the version is below 2.3.0
  4. Check for unauthorized coupon creation capability
    Inspect the roles and capabilities on the site using a role editor plugin or by examining user accounts. Look for any user roles other than Administrator that have access to coupon creation or coupon management screens, or check if lower-privileged users (like Shop Managers or Subscribers) can access the Smart Coupons admin interface at wc-admin&page=smart_coupons.
    Affected if Non-administrator users (such as Shop Managers, Editors, or lower roles) can access the coupon management functionality when they should not be able to

The site is affected if the WebToffee Smart Coupons for WooCommerce plugin is installed, active, and running a version earlier than 2.3.0, allowing unauthorized users to access coupon management functions they should not have permission to use.
