WordPress · Colissimo Officiel : Méthodes De Livraison Pour Woocommerce · CVE-2026-9240
**Name of the Vulnerable Software and Affected Versions**
Colissimo Officiel : Méthodes de livraison pour WooCommerce versions prior to 2.9.1
**Description**
Authenticated users with Subscriber-level access and above can perform unauthorized modification of data. The issue exists because the `updateShippingMethod()` function, registered to the `wp ajax lpc order affect` AJAX action, fails to perform a `current user can()` capability check and lacks nonce verification. This allows an attacker to provide a specific `order id` to modify the shipping method, pickup-point meta, and shipping address of arbitrary WooCommerce orders, including those belonging to other users.
**Recommendations**
Update to a version newer than 2.9.0.
As a temporary workaround, restrict access to the `updateShippingMethod()` function until a patch is applied.
