CVE-2026-87846: Shipping for Nova Poshta 1.18.7 - 1.19.8 - Unauthenticated Order Shipment Record Deletion
The Shipping for Nova Poshta WordPress plugin through 1.19.8 does not perform any authorisation, nonce or ownership checks on one of its AJAX actions available to unauthenticated users, allowing anyone to delete the shipment records of arbitrary orders and to make the store issue the carrier's waybill-deletion request for those orders using the store's own stored API credentials.
