It carries a CVSS score of 8.2 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication.

Vulnerability Overview

The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.1.2 via the 'file_url' parameter. This makes it possible for unauthenticated attackers to view potentially sensitive information and download a digital product without paying for it.

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-201: Insertion of Sensitive Information Into Sent Data

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Remediation

Update to version 5.1.3, 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: Simple Shopping Cart 5.1.3 closes this, and updating the plugin is the step that ends it.
