Low risk5th percentile - higher than 5% of all known CVEs
Summary
The BitPay Gateway for WooCommerce WordPress plugin through 4.1.3 does not bind the payment provider's transaction confirmation to the order it completes, nor verify the confirmed amount. This allows an unauthenticated attacker holding a single genuine low-value transaction to mark arbitrary higher-value orders as paid.
Risk Assessment
An attacker can obtain high-value goods or services while paying only for a single low-value transaction, leading to direct financial losses. The risk affects all WooCommerce stores using this gateway.
Recommendation
Update the BitPay Gateway for WooCommerce plugin to a version later than 4.1.3 if available, or implement additional verification binding transactions to orders and amounts. Monitor for unusual discrepancies between transaction amounts and order values.
