Description
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. Since the X-Forwarded-* headers do have valid use cases, particularly in clustered environments using a load balancer, the library offers mitigation measures only in the v2 releases, as doing otherwise would break these use cases immediately. Users of v2 releases from 2.11.1 can provide an additional argument to Laminas\Diactoros\ServerRequestFactory::fromGlobals() in the form of a Laminas\Diactoros\RequestFilter\RequestFilterInterface instance, including the shipped Laminas\Diactoros\RequestFilter\NoOpRequestFilter implementation which ignores the X-Forwarded-* headers. Starting in version 3.0, the library will reverse behavior to use the NoOpRequestFilter by default, and require users to opt-in to X-Forwarded-* header usage via a configured Laminas\Diactoros\RequestFilter\LegacyXForwardedHeaderFilter instance. Users are advised to upgrade to version 2.11.1 or later to resolve this issue. Users unable to upgrade may configure web servers to reject X-Forwarded-* headers at the web server level.
