Descriptions

In certain conditions, depending on timing and the usage of the Chrome web browser, Guardian/CMC versions before 22.6.2 do not always completely invalidate the user session upon logout. Thus an authenticated local attacker may gain acces to the original user's session.

*Credits: This issue was confirmed by Nozomi Networks after a bug reported by one of our Customers.
