CVE-2025-14146
Booking Calendar <= 10.14.10 - Unauthenticated Sensitive Information Exposure
The Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 10.14.10 via the WPBC_FLEXTIMELINE_NAV AJAX action. This is due to the nonce verification being conditionally disabled by default (booking_is_nonce_at_front_end option is 'Off' by default). When the booking_is_show_popover_in_timeline_front_end option is enabled (which is the default in demo installations and can be enabled by administrators), it is possible for unauthenticated attackers to extract sensitive booking data including customer names, email addresses, phone numbers, and booking details.
