apollo-portal has potential CSRF issue

Apollo is a configuration management system. Prior to version 2.1.0, a low-privileged user can create a special web page. If an authenticated portal admin visits this page, the page can silently send a request to assign new roles for that user without any confirmation from the Portal admin. Cookie SameSite strategy was set to Lax in version 2.1.0. As a workaround, avoid visiting unknown source pages.
