Vulnerability Overview

The Order Tracking – WordPress Status Tracking Plugin plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 3.5.0. This makes it possible for unauthenticated attackers to forge payment confirmations and bypass payments.

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.

CWE-345: Insufficient Verification of Data Authenticity

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.

Remediation

Update to version 3.6.0, 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: Order Tracking 3.6.0 closes this, and updating the plugin is the step that ends it.
