## Description

The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.7.6, due to the order save handler loading a transaction by its client-supplied 'id' without verifying that it belongs to the order being saved. This makes it possible for authenticated attackers, with LatePoint Agent-level access and above, to reassign and modify transaction records belonging to orders outside their allowed records.
