CVE-2024-31265Network attack vector

Coupon modification via missing AJAX nonce validation

Published Apr 12, 2024 · Updated Apr 28, 2026

Cross-site request forgery in SumoMe Sumo 1.34 and earlier allows remote attackers to add or remove WooCommerce coupons. The ajax_sumo_add_woocommerce_coupon and ajax_sumo_remove_woocommerce_coupon functions accept state-changing requests without valid nonce verification. Exploitation requires an administrator with an authenticated WordPress session to open an attacker-controlled link, after which coupons can be added or removed.
