## Description

Symfony is a PHP framework for web and console applications and a set of
reusable PHP components. The Symfony form component provides a CSRF
protection mechanism by using a random token injected in the form and using
the session to store and control the token submitted by the user. When
using the FrameworkBundle, this protection can be enabled or disabled with
the configuration. If the configuration is not specified, by default, the
mechanism is enabled as long as the session is enabled. In a recent change
in the way the configuration is loaded, the default behavior has been
dropped and, as a result, the CSRF protection is not enabled in form when
not explicitly enabled, which makes the application sensible to CSRF
attacks. This issue has been resolved in the patch versions listed and
users are advised to update. There are no known workarounds for this issue.
