CVE-2026-9240Network attack vector

Subscriber-level order shipment modification via unchecked AJAX handler

Published Jul 9, 2026 · Updated Jul 9, 2026

Missing authorization in Colissimo shipping methods for WooCommerce 2.9.0 and earlier allows remote authenticated users to alter order shipping data. The updateShippingMethod function behind the wp_ajax_lpc_order_affect action reads an attacker-supplied order_id without a capability check or nonce verification, then rewrites the selected order's shipping method, pickup-point metadata, and shipping address. Subscriber-level access is sufficient, and the target order can belong to another user.
