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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
