{"id":"CVE-2026-104012","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-104012","summary":"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,…","details":"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).","published":"2026-10-31T08:16:47.893","modified":"2026-10-31T08:16:47.893","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://downloads.wordpress.org/plugin/rox-appointment-booking.1.3.2.zip"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/Customer/Data/CustomerModel.php#L38"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/Customer/REST/SaveCustomer.php#L262"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/FrontendBookingPanel/REST/BookingConfirm.php#L61"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/rox-appointment-booking/tags/1.3.0/src/Modules/FrontendBookingPanel/Services/CustomerService.php#L74"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2a32f428-fa6e-469b-b004-e80a1029af80?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-31T08:16:47.893"}}
