Vulnerability Overview

The WooCommerce - PDF Vouchers plugin for WordPress is vulnerable to authentication bypass in all versions up to 4.9.9 (exclusive). This makes it possible for unauthenticated attackers to log in as other users.

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 confidentiality, integrity, availability — full site compromise territory.

CWE-288: Authentication Bypass Using an Alternate Path or Channel

Reaching this weakness in WooCommerce - PDF Vouchers < 4.9.9 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For WooCommerce - PDF Vouchers the fix is 4.9.9: builds < 4.9.9 are affected, anything from 4.9.9 onward is not.

Remediation

Update to version 4.9.9, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WooCommerce - PDF Vouchers 4.9.9 closes this, and updating the plugin is the step that ends it.
