An issue was discovered in the Security component in Symfony 2.7.x before
2.7.48, 2.8.x before 2.8.41, 3.3.x before 3.3.17, 3.4.x before 3.4.11, and
4.0.x before 4.0.11. By default, a user’s session is invalidated when the
user is logged out. This behavior can be disabled through the
invalidate_session option. In this case, CSRF tokens were not erased during
logout which allowed for CSRF token fixation.
