## Description

In OpenStack Zaqar before 23.0.1, the WebSocket transport fails to bind the project identifier in subsequent requests to the project authenticated by the Keystone token. An authenticated user with a valid token for one project may substitute another project's UUID to enumerate, inspect, create, or delete queues belonging to that project, resulting in unauthorized disclosure, modification, or loss of queue data. Only deployments using the WebSocket transport with Keystone authentication are affected.
