CVE-2026-103365 Details
Description
The Bookly – Online Scheduling and Appointment Booking System plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 28.4 via the classic booking form's Details step. The endpoint bookly_render_details is registered for both wp_ajax and wp_ajax_nopriv, the module overrides csrfTokenValid() to always return true, and Bookly\Frontend\Components\Booking\InfoText::getCodes() calls UserBookingData::getCustomer() to load the persisted Customer entity keyed solely by the attacker-supplied phone (or email) with no invocation of the plugin's own customerIdentityConfirmed() predicate. When a site owner has placed the supported {client_name}, {client_email}, {client_phone}, or {client_note} placeholders into the Details step's Appearance information text, the matched customer's stored name, email, phone and internal notes are substituted into the returned HTML. This makes it possible for unauthenticated attackers who know only a registered customer's primary phone (or email) to read that customer's stored personal data.
A vulnerability allowing sensitive information exposure has been identified in the Bookly – Online Scheduling and Appointment Booking System plugin for WordPress, affecting versions through 28.4. The issue arises in the classic booking form's Details step, where the endpoint 'bookly_render_details' is accessible to both authenticated and unauthenticated users. The vulnerability is compounded by the module's csrfTokenValid() function, which incorrectly validates CSRF tokens. The 'getCodes()' method retrieves customer data based solely on an attacker-provided phone number or email, without verifying the customer's identity. If the site owner has included certain placeholders in the Details step's Appearance text, the corresponding customer's personal information is exposed. This allows unauthenticated attackers to access the personal data of registered customers by knowing their primary phone number or email.
Users are advised to update the Bookly – Online Scheduling and Appointment Booking System plugin to version 28.5 or a newer patched version.
