Short explanation

An Insecure Direct Object Reference vulnerability in the FunnelKit Payment Gateway for Stripe WooCommerce plugin allows unauthenticated attackers to read sensitive billing personal data by enumerating sequential order IDs.

Why does it matter?

This vulnerability permits the exposure of complete billing personally identifiable information without requiring authentication. Because the plugin script call operates independently of WooCommerce order validation, exploitation occurs even on rejected requests.

What should be done?

  • Follow vendor advisories as patch status is currently unknown
  • Monitor for official plugin updates and fixes
  • Review custom validation rules for order-pay parameters

Show the technical text from the sources

The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.15.0.2 via the 'order-pay (WP query var from /checkout/order-pay/<ID>/)' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to read the full billing PII — including name, email address, phone number, and complete street address — of any store order by enumerating sequential order IDs, as this data is emitted into the inline fkwcs_data JavaScript object via wp_localize_script on every matching page response. Exploitation occurs even when WooCommerce itself rejects the order-pay page request, because the plugin's wp_localize_script call runs independently of WooCommerce's own order-key validation on the same request.
