CVE-2025-14146Network attack vector

Unauthenticated booking data exposure via disabled nonce

Published Jan 9, 2026 · Updated Jan 9, 2026

Missing authorization in wpdevelop Booking Calendar 10.14.10 and earlier allows remote attackers to read customer booking data. The WPBC_FLEXTIMELINE_NAV AJAX action skips nonce verification because booking_is_nonce_at_front_end is Off by default, exposing names, email addresses, phone numbers, and booking details. The endpoint is reachable without authentication only when booking_is_show_popover_in_timeline_front_end is enabled, which is the default for demo installations.
