Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-326.
Summary
The Booking Package WordPress plugin before 1.7.31 derives booking cancellation tokens from values it exposes publicly instead of a secure source of randomness, which is weak cryptographic strength (CWE-326). An unauthenticated remote attacker can reconstruct a booking's token to view that booking's personal data and, where visitor cancellation is enabled, cancel the booking. A public exploit is linked in the references.

Description from the CNA
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.
