CVE-2026-9240
Colissimo Officiel : Méthodes de livraison pour WooCommerce <= 2.9.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Order Shipment Modification via lpc_order_affect AJAX action
Description
The Colissimo Officiel : Méthodes de livraison pour WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the updateShippingMethod() function (registered to the wp_ajax_lpc_order_affect AJAX action) in versions up to, and including, 2.9.0. This is due to the handler performing no current_user_can() capability check and no nonce verification before reading an attacker-supplied order_id and modifying that order's shipping method, pickup-point meta, and shipping address. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create or modify the shipment information (shipping method, pickup relay data, and shipping address) of arbitrary WooCommerce orders, including orders placed by other users.
