CVE-2026-3430Public exploitNetwork attack vector

Database disclosure via abandoned-cart SQL injection

Published Aug 6, 2026 · Updated Aug 6, 2026

SQL injection in Constant Contact Creative Mail 1.6.5 through 1.6.9 allows remote attackers to obtain database data through a crafted AJAX request. The ce4wp_abandoned_checkouts_capture_guest_checkout action inserts the ce4wp-recover query value into an SQL statement without sanitization or escaping. Exploitation requires a guest-checkout WooCommerce nonce and Creative Mail management of abandoned-cart email; the demonstrated impact is indirect disclosure through a time-delay oracle.
