GHSA-g4g7-q726-v5hg
Cross-Site Request Forgery (CSRF) 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.

CVE-2016-1902
GHSA-jjx5-fq5g-8xpc
Cryptographic Issues The `nextBytes` function in the `SecureRandom` class in Symfony does not properly generate random numbers when used with PHP without the `paragonie/random_compat` library and the `openssl_random_pseudo_bytes` function fails, which makes it easier for attackers to defeat cryptographic protection mechanisms via unspecified vectors.
