The advisory
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.
