How to fix?

Upgrade parse-server to version 4.10.15, 5.2.6 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 Authentication Bypass where the session object properties can be updated by a foreign user if the object ID is known.

Workaround

If upgrading to the fixed version is not possible, users can add a beforeSave trigger to the _Session class and prevent writing, if the requesting user is different from the user in the session object.
