Hi,

The following vulnerability was published for symfony.

CVE-2023-46733[0]:
| 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.


If you fix the vulnerability please also make sure to include the
