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)."}],"title":"Rox Appointment Booking <= 1.3.1 - Unauthenticated Privilege Escalation via Mass Assignment to Mass Assignment via '/public/booking' Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2a32f428-fa6e-469b-b004-e80a1029af80?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/Customer/REST/SaveCustomer.php#L262"},{"url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/FrontendBookingPanel/Services/CustomerService.php#L74"},{"url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/Customer/Data/CustomerModel.php#L38"},{"url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/FrontendBookingPanel/REST/BookingConfirm.php#L61"},{"url":"https://downloads.wordpress.org/plugin/rox-appointment-booking.1.3.2.zip"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Daryle Minor"}],"timeline":[{"time":"2026-10-11T10:02:19.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T19:18:58.000Z","lang":"en","value":"Disclosed"}]}}}
