CSRF Token Fixation Vulnerability in Symfony

CVE-2018-11406 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

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.
