At a glance
CVE-2026-9284 is a high-severity Missing Authorization vulnerability in the WooCommerce PayPal Payments WordPress plugin, affecting versions <= 4.0.1. It carries a CVSS score of 8.2 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 4.0.2; sites on affected versions should update now. Disclosed May 2026, reported by Dmitrii Ignatyev.
Vulnerability Overview
The WooCommerce PayPal Payments plugin for WordPress is vulnerable to unauthorized order manipulation and information disclosure due to missing authorization checks on the `ppc-create-order` and `ppc-get-order` WC-AJAX endpoints in all versions up to, and including, 4.0.1. The `ppc-create-order` endpoint accepts an arbitrary WooCommerce order ID in the `pay-now` context without validating order ownership, allowing attackers to create PayPal orders for any WC order and write PayPal metadata to it. The `ppc-get-order` endpoint returns full PayPal order details for any PayPal order ID without binding to the requester's session. This makes it possible for unauthenticated attackers to chain these endpoints to manipulate other customers' order payment flows and exfiltrate sensitive order details (payer information, shipping data) by creating a PayPal order for a victim's WC order and then retrieving the PayPal order data.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-862: Missing Authorization
Reaching this weakness in WooCommerce PayPal Payments <= 4.0.1 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For WooCommerce PayPal Payments the fix is 4.0.2: builds <= 4.0.1 are affected, anything from 4.0.2 onward is not.
Remediation
Update to version 4.0.2, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: WooCommerce PayPal Payments 4.0.2 closes this, and updating the plugin is the step that ends it.
