Upgrade symfony/security-http to version 5.3.2 or higher.
Overview
symfony/security-http is a provides an infrastructure for sophisticated authorization systems, which makes it possible to easily separate the actual authorization logic from so called user providers that hold the users credentials.
Affected versions of this package are vulnerable to Improper Authentication. When an application defines multiple firewalls, the authenticated token delivered by one of the firewalls is available to all other firewalls. This can be abused when the application defines different providers for different parts of an application. In such a situation, a user authenticated on one part of the application is considered authenticated on the whole application.
