At a glance

CVE-2025-7820 is a high-severity Client-Side Enforcement of Server-Side Security vulnerability in the SKT PayPal for WooCommerce WordPress plugin, affecting versions <= 1.4. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication.

Vulnerability Overview

The SKT PayPal for WooCommerce plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 1.4. This is due to the plugin only enforcing client side controls instead of server-side controls when processing payments. This makes it possible for unauthenticated attackers to make confirmed purchases without actually paying for them.

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 integrity.

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 1.5, 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: SKT PayPal for WooCommerce 1.5 closes this, and updating the plugin is the step that ends it.
