On pages where an authenticated user can trigger an exception which is then displayed to the user as "Internal error" dialog with details about the exception, it was possible for the user to inject javascript code which was executed in the context of the authenticated user.
This has been fixed that javascript/html code which is injected is being escaped correctly.
