How to fix?

Upgrade parse-server to version 4.5.1 or higher.

Overview

parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.

Affected versions of this package are vulnerable to Information Exposure. When an anonymous user is first signed up using REST, the server creates session incorrectly. Particularly, the authProvider field in _Session class under createdWith shows the user logged in creating a password. If a developer later depends on the createdWith field to provide a different level of access between a password user and anonymous user, the server incorrectly classified the session type as being created with a password. The server does not currently use createdWith to make decisions about internal functions, so if a developer is not using createdWith directly, they are not affected. The vulnerability only affects users who depend on createdWith by using it directly.
