[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-3972) identity login security bug

[David Croe (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBSEAM-3972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Croe updated JBSEAM-3972:
-------------------------------

    Description: 
Hello !
I think there is a major security bug in the seamspace example, which will give a user the permissions of the user which has been logged in before.
To reproduce the scenario:
1. login as user demo.
2. click the back button or enter the login page manually in the url of your browser
3. login as another user.
the second user will have the admin permissions of the demo user!
Problem is that the authenticate method will not be invoked if you are already logged in ( even as another user) and the old principal with the assigned permissions will stay in memory.

Greetings
 D.Croe
