The Hydra Booking plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the tfhb_reset_password_callback() function in versions 1.1.0 to 1.1.18. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset the password of an Administrator user, achieving full privilege escalation.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
