CVE-2025-14146: CWE-862 Missing Authorization in wpdevelop Booking Calendar
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.
AI Analysis
Technical Summary
CVE-2025-14146 is a Missing Authorization vulnerability in the Booking Calendar WordPress plugin by wpdevelop. The issue arises because the nonce verification for the AJAX action `WPBC_FLEXTIMELINE_NAV` is conditionally disabled by default due to the `booking_is_nonce_at_front_end` option being set to 'Off'. When the `booking_is_show_popover_in_timeline_front_end` option is enabled (default in demo installations), unauthenticated attackers can retrieve sensitive booking data such as customer names, emails, phone numbers, and booking details. This exposure results from insufficient access control on the AJAX endpoint.
Potential Impact
An unauthenticated attacker can access sensitive customer booking information including names, email addresses, phone numbers, and booking details. This leads to sensitive information exposure but does not affect integrity or availability. The CVSS score of 5.3 reflects a medium severity impact focused on confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should consider disabling the `booking_is_show_popover_in_timeline_front_end` option or enabling nonce verification (`booking_is_nonce_at_front_end`) to prevent unauthorized access. Monitoring vendor channels for updates is recommended.
