CVE-2026-9240: CWE-862 Missing Authorization in iscpcolissimo Colissimo shipping methods for WooCommerce
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.
AI Analysis
Technical Summary
CVE-2026-9240 describes a missing authorization vulnerability (CWE-862) in the Colissimo Officiel plugin for WooCommerce. The updateShippingMethod() function, triggered by the wp_ajax_lpc_order_affect AJAX action, lacks a current_user_can() capability check and nonce verification. As a result, authenticated attackers with minimal privileges can supply an order_id and modify shipment information of orders they do not own. This vulnerability affects all versions up to and including 2.9.0 of the plugin.
Potential Impact
An attacker with Subscriber-level or higher access can alter shipping methods, pickup relay data, and shipping addresses of arbitrary WooCommerce orders. This unauthorized modification can lead to order fulfillment errors, potential fraud, or disruption of shipping processes. There is no impact on confidentiality or availability reported, but integrity of order shipment data is compromised.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict user roles to trusted users only and monitor for suspicious changes to order shipment data. Avoid granting Subscriber-level or higher access to untrusted users. Follow vendor updates for an official patch or temporary fix.
