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.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
