Summary

The Symfony PHP framework, widely used for web and console applications, has a security issue where it fails to clear CSRF tokens during user session regeneration upon login. This oversight allows same-site attackers to potentially exploit the CSRF protection mechanism, thereby facilitating a session fixation attack.
