Symfony is a PHP framework for web and console applications and a set of
reusable PHP components. Starting in versions 5.4.21 and 6.2.7 and prior to
versions 5.4.31 and 6.3.8, SessionStrategyListener
does not migrate the
session after every successful login. It does so only in case the logged in
user changes by means of checking the user identifier. In some use cases,
the user identifier doesn’t change between the verification phase and the
successful login, while the token itself changes from one type
(partially-authenticated) to another (fully-authenticated). When this
happens, the session id should be regenerated to prevent possible session
fixations, which is not the case at the moment. As of versions 5.4.31 and
6.3.8, Symfony now checks the type of the token in addition to the user
identifier before deciding whether the session id should be regenerated.
