Unauthenticated payment bypass via unvalidated callback
Published Nov 4, 2025 · Updated Nov 4, 2025
Payment bypass in BeycanPress Payeer Payment Gateway for WooCommerce 1.0.3 and earlier allows remote attackers to mark orders paid. The /wc-api/bp-payeer-gateway-callback endpoint accepts callbacks without server-side payment-status validation and updates unpaid WooCommerce orders as paid. No authentication is required; forged callbacks can release goods or services without payment and cause merchant revenue loss.
