Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

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.
