CVE, Research URL: CVE-2026-105193
Home page URL: Security reports for WP Booking Calendar
Application: WP Booking Calendar
Published on: Oct 08, 2026
Research 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.
Affected versions: max 11.8.
Status: vulnerable
