 "title": "Shipping for Nova Poshta <= 1.19.8 - Reflected Cross-Site Scripting via 'invoice' Parameter",
 "description": "The nova-poshta-ttn plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'invoice' parameter on the 'Мої накладні' (morkvanp_invoices) waybill edit admin page in all versions up to, and including, 1.19.8. This is due to the parameter being echoed into the form action attribute without sanitization or output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that run if they can trick a logged-in administrator or shop manager into clicking a crafted link.",
