CVE-2026-39541

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. This allows 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.

The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.3 does not verify that the host record being modified belongs to the user making the request. This allows authenticated users holding a Hydra Booking-assigned host role to modify other hosts' profile data and reassign ownership of another host's record to themselves.

The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.2 does not verify that a booking belongs to the requesting user before modifying or deleting it on two of its booking endpoints. This allows a booking-provider-level user to cancel and permanently delete other providers' bookings on the same site.
