Executive brief
The WooCommerce PayPal Payments plugin for WordPress, which handles payment processing for online stores, contains a security flaw that allows unauthorized individuals to access and manipulate customer orders. An attacker can view sensitive information such as customer names and shipping addresses, and potentially interfere with the payment process for existing orders. This could lead to data breaches and operational disruptions for e-commerce businesses using this plugin.
Technical details
The vulnerability stems from missing authorization checks on the `ppc-create-order` and `ppc-get-order` WC-AJAX endpoints. The `ppc-create-order` endpoint allows an unauthenticated attacker to provide an arbitrary WooCommerce order ID and create a corresponding PayPal order without verifying ownership, which writes PayPal metadata to the original order. By chaining this with the `ppc-get-order` endpoint—which returns full PayPal order details for any ID without session binding—an attacker can exfiltrate sensitive PII including payer information and shipping data. This is classified as a Missing Authorization (CWE-862) issue and affects all versions up to and including 4.0.1.
