How to fix?

Upgrade channels to version 3.0.3 or higher.

Overview

channels is a Developer-friendly asynchrony for Django.

Affected versions of this package are vulnerable to Information Exposure. The legacy channels.http.AsgiHandler class, used for handling HTTP type requests in an ASGI environment prior to Django 3.0, did not correctly separate request scopes in Channels 3.0. In many cases this would result in a crash but, with correct timing responses could be sent to the wrong client, resulting in potential leakage of session identifiers and other sensitive data.
