CVE-2020-36841Network attack vector

Unauthenticated gift-certificate creation via unchecked admin hook

Published Oct 16, 2024 · Updated Apr 8, 2026

Authorization bypass in WooCommerce Smart Coupons before 4.6.5 allows remote attackers to create arbitrary-value gift certificates. The woocommerce_coupon_admin_init function accepts gift-certificate parameters through admin-post.php and calls send_gift_certificate without checking manage_woocommerce. Unauthenticated access is sufficient, and the resulting store credit can be redeemed for merchandise on the affected storefront.
