DescriptionCVE.org

The Payment Plugins for Stripe WooCommerce WordPress plugin before 4.0.12 does not validate the order key before adding order data to the JavaScript configuration it outputs on the front end, allowing unauthenticated users to obtain the billing details of any order, together with the secret that gates access to it, by iterating sequential order identifiers.

The root cause is missing order key validation before order data is serialized into the plugin's client-side configuration, combined with WooCommerce's use of sequential, predictable order identifiers that make enumeration trivial. …
