CVE-2026-104766
Appointment Booking Plugin <= 5.7.3 - Authenticated (Custom+) Privilege Escalation to 'settings[default_wp_role_for_customer]' Parameter
The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.7.3. This is due to the OsSettingsController::update() handler iterating over attacker-supplied settings parameters without an allowlist of permitted setting names or values, and OsSettingsHelper::prepare_value() performing no role allowlist validation before persisting the default_wp_role_for_customer setting — a restriction that exists only in the UI dropdown and is never enforced server-side. This makes it possible for authenticated attackers holding a LatePoint role with the settings__edit capability (such as an agent or custom role) to overwrite the default WordPress role for new customers with administrator, causing any subsequently self-registered LatePoint customer account to be created with full WordPress administrator privileges. Exploitation requires that a WordPress administrator has granted the settings__edit capability to a LatePoint agent or custom role, and that a new customer account is registered through LatePoint after the malicious setting change is persisted.
