Check the token in your action using the same token ID.

// $csrfProvider being an instance of Symfony\Component\Security\Csrf\TokenGenerator\TokenGeneratorInterface
if (!$csrfProvider->isCsrfTokenValid('rm_user_'.$user->getId(), $token)) {
    throw new \RuntimeException('CSRF attack detected.');
}
