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.
CVE-2025-14146 is a medium severity with CVSS 5.3 Sensitive Information Exposure issue affecting the Plugin Booking Calendar. It affects Versions up to 10.14.10 and is fixed in 10.14.11.
CVE-2025-14146 is tracked for the Plugin Booking Calendar as medium severity with CVSS 5.3. The affected range is Versions up to 10.14.10. Update Booking Calendar to 10.14.11 or newer where that version is compatible with the site.
