Short explanation
The Rox Appointment Booking plugin up to version 1.3.1 is vulnerable to privilege escalation via mass assignment through a public REST endpoint. This allows an unauthenticated attacker to persist an arbitrary WordPress user ID within customer records.
This vulnerability enables an attacker to overwrite an administrator's email address when an administrator updates the poisoned customer record, leading to full account takeover via standard password reset requests.
What should be done?
- Follow vendor advisories and security updates.
- Update the plugin to a secured version where available.
- Review privilege management and input validation controls.
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
The Rox Appointment Booking – Appointment Booking Scheduling Solution plugin for WordPress is vulnerable to Privilege Escalation via Mass Assignment in all versions up to, and including, 1.3.1 This is due to the public `/rox-appointment-booking/v1/public/booking` REST endpoint performing mass-assignment of the raw request body into a new customer row while `CustomerModel::$fillable` includes the internal `wp_user_id` column, allowing an unauthenticated attacker to persist an arbitrary WordPress user ID alongside an attacker-controlled email address with no authorization check. When an administrator subsequently opens the poisoned customer record and clicks Update Customer, `SaveCustomer::handleRequest()` passes the stored `wp_user_id` and attacker-supplied email to `wp_update_user()` — succeeding because `LinkedAccount::canChange()` unconditionally returns true when the acting user holds the `edit_users` capability — thereby overwriting the targeted administrator's email address and enabling full account takeover via a standard WordPress password-reset request. Successful exploitation requires an administrator to open and save the poisoned record, and the attacker must know or guess a valid administrator user ID (such as the default user ID 1).
