description

Appointment Booking Plugin versions before 5.6.5 can allow staff accounts restricted to specific records to delete orders, customers, or transactions outside their assigned scope. An attacker needs an authenticated backend staff account with a record-scoped role.

mitigation

Upgrade Appointment Booking Plugin to version 5.6.5 or later. Review backend staff accounts and limit access to trusted users until the update is applied.
