Vulnerability Overview
The CoCart plugin for WordPress is vulnerable to Payment Bypass in versions up to, and including, 4.8.0. 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 is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.
Remediation
Update to version 4.9.0, 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: CoCart 4.9.0 closes this, and updating the plugin is the step that ends it.
