Vulnerability Overview

The PAYCOMET for WooCommerce plugin for WordPress is vulnerable to Payment Bypass in versions 5.36 through 5.45. This is due to a lack of server-side payment verification. This makes it possible for unauthenticated attackers to 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-602: Client-Side Enforcement of Server-Side Security

The product includes a server that relies on the client to implement a protection mechanism that is intended to protect the server.

Remediation

Update to version 5.46, 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: PAYCOMET for WooCommerce 5.46 closes this, and updating the plugin is the step that ends it.
