Symfony potential Cross-site Scripting vulnerabilities in CodeExtension filters
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Starting in versions 2.0.0, 5.0.0, and 6.0.0 and prior to versions 4.4.51, 5.4.31, and 6.3.8, some Twig filters in CodeExtension use `is_safe=html` but don't actually ensure their input is safe. As of versions 4.4.51, 5.4.31, and 6.3.8, Symfony now escapes the output of the affected filters.

Symfony has an Authentication Bypass via RememberMe
### Description

When consuming a persisted remember-me cookie, Symfony does not check if the username persisted in the database matches the username attached with the cookie, leading to authentication bypass.

### Resolution

The `PersistentRememberMeHandler` class now ensures the submitted username is the cookie owner.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/81354d392c5f0b7a52bcbd729d6f82501e94135a) for branch 5.4.

### Credits

We would like to thank Moritz Rauch - Pentryx AG for reporting the issue and Jérémy Derussé for providing the fix.

Withdrawn Advisory: Symfony http-security has authentication bypass
## Withdrawn Advisory
This advisory has been withdrawn because the report is not part of a valid vulnerability. This link is maintained to preserve external references. For more information, see advisory-database/pull/5046.

## Original Description
In Symfony, a security vulnerability was identified in the FormLoginAuthenticator component, where it failed to adequately handle cases where the username or password field of a login request is empty. This flaw could lead to various security risks, including improper authentication logic handling or denial of service.

Cross-site scripting
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Starting in version 6.0.0 and prior to version 6.3.8, the error message in `WebhookController` returns unescaped user-submitted input. As of version 6.3.8, `WebhookController` now does not return any user-submitted input in its response.

Authentication granted to all firewalls instead of just one
Description
-----------

When an application defines multiple firewalls, the authenticated token delivered by one of the firewalls is available to all other firewalls. This can be abused when the application defines different providers for different parts of an application. In such a situation, a user authenticated on one part of the application is considered authenticated on the whole application.

Resolution
----------

We now ensure that the authenticated token is only available for the firewall that generates it.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/3084764ad82f29dbb025df19978b9cbc3ab34728) for branch 5.3.
