CVE-2018-11406: CSRF

Published May 25, 2018
·
Updated

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 invalidatesession option. In this case, CSRF tokens were not erased during logout which allowed for CSRF token fixation.
