Executive brief
The WooCommerce PayPal Payments plugin for WordPress, which handles payment processing for online stores, contains a security flaw that allows unauthorized access to order data. An attacker can exploit this to obtain sensitive customer information, including names, email addresses, phone numbers, and physical addresses, shortly after a purchase is made. This could lead to privacy breaches and potential targeted phishing attacks against recent customers.
Technical details
The WooCommerce PayPal Payments plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) classified as CWE-639. The flaw exists within the `enqueue_paypal_insights_script_on_order_received()` function due to a lack of validation on a user-controlled key. An unauthenticated remote attacker can exploit this to retrieve sensitive order keys. These keys can subsequently be used to query the WooCommerce Store API to access full customer billing details, provided the request is made within a 10-minute grace period following the order's creation. The issue is addressed in version 3.4.0.
