DPD Baltic Shipping <= 1.2.8 is vulnerable to WordPress WooCommerce Shipping - DPD baltic plugin <= 1.2.8 - Auth. Stored Cross-Site Scripting (XSS) vulnerability

The DPD Baltic Shipping plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the shipping terminal parameters (ex: 'wc_shipping_(idnumber)_terminal') in versions up to, and including, 1.2.8 due to insufficient input sanitization and output escaping. This makes it possible for administrator-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
