## Technical details

The Colissimo Officiel plugin for WordPress fails to perform authorization checks and nonce verification in the updateShippingMethod() function, which is tied to the wp_ajax_lpc_order_affect AJAX action. This missing capability check (current_user_can) allows authenticated attackers with Subscriber-level permissions or higher to modify order metadata. By supplying an arbitrary order_id, an attacker can change the shipping method, pickup-point metadata, and shipping address of any WooCommerce order. The issue is present in versions up to and including 2.9.0.
