Hydra Booking < 1.2.4 - Hydra Host+ Cross-Host Account Modification and Deletion via IDOR

The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.4 does not perform object-level authorisation checks on several of its host-management operations, allowing users who hold its own administrator-assigned custom role to read, modify and permanently delete other hosts' records and the WordPress user accounts linked to them.
