CSRF token is tied to a non-session cookie:
This situation is harder to exploit but is still vulnerable. If the web site contains any behavior that allows an attacker to set a
cookie in a victim’s browser, then an attack is possible. The attacker can log in to the application using their own account, obtain
a valid token and associated cookie, leverage the cookie-setting behavior to place their cookie into the victim’s browser, and feed
their token to the victim in their CSRF attack.
