## Description

The Fluent Support – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Missing Authorization via the 'agent_id' parameter of the agent ticket creation REST endpoint in all versions up to, and including, 2.4.7, due to the endpoint not checking the 'Assign Agents' permission before storing a submitted agent_id on the new ticket. This makes it possible for authenticated support agents who may manage tickets but not assign agents to create tickets assigned to any agent.
