laminas-diactoros is a PHP package containing implementations of the PSR-7 HTTP message interfaces and PSR-17 HTTP message factory interfaces. Applications that use Diactoros, and are either not behind a proxy, or can be accessed via untrusted proxies, can potentially have the host, protocol, and/or port of a `Laminas\Diactoros\Uri` instance associated with the incoming server request modified to reflect values from `X-Forwarded-*` headers. Such changes can potentially lead to XSS attacks (if a fully-qualified URL is used in links) and/or URL poisoning. https://github.com/laminas/laminas-diactoros/commit/25b11d422c2e5dad868f68619888763b30f91e2d https://github.com/laminas/laminas-diactoros/security/advisories/GHSA-8274-h5jp-97vr https://portswigger.net/web-security/host-header
