CSRF protection tokens did not expire

By default, CSRF tokens in Jenkins only checked user authentication and IP address. This allowed attackers able to obtain a CSRF token for another user to implement CSRF attacks as long as the victim's IP address remained unchanged. CSRF tokens will now also check the web session ID to confirm th...
