## Overview

The PDF Invoices & Packing Slips for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Billing First Name / Last Name / Company Fields in all versions up to, and including, 5.16.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload survives initial storage because WooCommerce's sanitize_text_field() and wc_clean() do not strip entity-encoded strings containing no literal '<' character, allowing unauthenticated guest-checkout orders to plant the malicious content.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
