Summary
Authentication granted to all firewalls instead of just one
Details

Description

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.

Resolution

We now ensure that the authenticated token is only available for the firewall that generates it.

The patch for this issue is available here for branch 5.3.
