CyberRota Analysis
AI-GeneratedThe TrueBooker Appointment Booking and Scheduler System plugin for WordPress is critically vulnerable to an authorization bypass that allows unauthenticated attackers to overwrite any user's email address, including that of administrators. This flaw stems from the absence of authentication checks in the admin_user_create_cus AJAX handler, enabling attackers to exploit the truebooker_wp_user_id parameter. WordPress site administrators using this plugin should prioritize immediate updates to version 1.2.7 or later to mitigate the risk of account takeover.
Original NVD Description
The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key leading to Account Takeover in all versions up to, and including, 1.2.6. This is due to the admin_user_create_cus AJAX handler lacking any authentication or capability check before passing the attacker-supplied truebooker_wp_user_id parameter directly to wp_update_user. This makes it possible for unauthenticated attackers to overwrite the email address of any WordPress user — including an administrator — and then complete the standard WordPress lost-password flow to fully take over the targeted account.
