Vulnerability Overview

The WooCommerce PDF Invoices & Packing Slips plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.2.5. This is due to missing or incorrect nonce validation on the attachment_settings_hint() function. This makes it possible for unauthenticated attackers to change the hide attachments setting hint via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

PDF Invoices & Packing Slips for WooCommerce <= 3.2.5 carries this weakness at attachment_settings_hint(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For PDF Invoices & Packing Slips for WooCommerce the fix is 3.2.6: builds <= 3.2.5 are affected, anything from 3.2.6 onward is not.

Remediation

Update to version 3.2.6, or a newer patched version

How does WordSec protect against this?
