The Booking Package WordPress plugin before 1.7.31 does not generate booking cancellation tokens using a secure source of randomness, deriving them instead from values it exposes publicly, so an unauthenticated attacker can reconstruct an arbitrary booking's token, disclose that booking's personal data and, where visitor cancellation is enabled, cancel the booking.

**Name of the Vulnerable Software and Affected Versions** Shipping for Nova Poshta WordPress plugin versions prior to 1.19.9 **Description** An issue exists where an AJAX action available to unauthenticated users lacks authorization, nonce, or ownership checks. This allows an attacker to delete shipment records of arbitrary orders and trigger waybill-deletion requests to the carrier using the store's stored API credentials. **Recommendations** Update Shipping for Nova Poshta WordPress plugin to version 1.19.9 or later.
