What is CVE-2025-14146?
CVE-2025-14146 is a medium-severity vulnerability in wpdevelop Booking Calendar, published on 9 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-862
