Original source description

The fix is distributed via Composer as ezsystems/ezplatform v2.5.4, and in v3.0.0 when that will be released.
If you'd like to manually enable it in your configuration, this is done by editing your app/config/security.yml and setting the "csrf_token_generator" key to "security.csrf.token_manager", like this:
security:
firewalls:
ezpublish_front:
form_login:
csrf_token_generator: security.csrf.token_manager
NB: In eZ Platform 3.0 this file has been moved to config/packages/security.yaml
