Description
The Booking Calendar WordPress plugin before 11.8 does not generate its per-booking access hashes with sufficient entropy, deriving each from a low-entropy time-seeded value, which can allow unauthenticated attackers who are able to determine a booking's creation time to predict the hash and then read that booking's personal data or modify the booking in place.
