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.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
`Symfony/Http-Kernel` is the HTTP kernel component for Symfony, a PHP framework for web and console applications and a set of reusable PHP components. Headers that are not part of the `trusted_headers` allowed list are ignored and protect users from Cache poisoning attacks. In Symfony, maintainers added support for the `X-Forwarded-Prefix` headers, but this header was accessible in SubRequest, even if it was not part of the `trusted_headers` allowed list. An attacker could leverage this opportunity to forge requests containing a `X-Forwarded-Prefix` header, leading to a web cache poisoning issue.

Withdrawn Advisory: Symfony http-security has authentication bypass
## Withdrawn Advisory
This advisory has been withdrawn because the report is not part of a valid vulnerability.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.
