PDF Invoices & Packing Slips for WooCommerce (5.16.2 before 5.16.5) fails to escape several customer-supplied order fields, including billing and shipping addresses and the customer order note, before writing them into generated invoices and packing slips. An unauthenticated visitor can place a guest order that stores a script. The script runs when a shop administrator views the document, as stored cross-site scripting.
What to do: Upgrade PDF Invoices & Packing Slips for WooCommerce to 5.16.5.

Description · NVD
The PDF Invoices & Packing Slips for WooCommerce WordPress plugin from 5.16.2 before 5.16.5 does not properly escape several customer-supplied order fields — including the billing and shipping address values and the customer order note — before they are output in generated invoice and packing-slip documents, allowing unauthenticated users placing guest orders to store a malicious script that executes when a shop administrator views the document, leading to Stored Cross-Site Scripting.
