Such changes can potentially lead to XSS attacks (if a fully-qualified URL is used in links) and/or URL poisoning.\n\n### Patches\n\nAny version after 2.11.0.\n\nStarting in laminas/laminas-diactoros 2.11.1, we have added `Laminas\\Diactoros\\ServerRequestFilter\\FilterServerRequestInterface`, which defines the single method `__invoke(Psr\\Http\\Message\\ServerRequestInterface $request): Psr\\Http\\Message\\ServerRequestInterface`. Filters implementing this interface allow modifying and returning a generated `ServerRequest`.\n\nThe primary use case of the interface is to allow modifying the generated URI based on the presence of headers such as `X-Forwarded-Host`. When operating behind a reverse proxy, the `Host` header is often rewritten to the name of the node to which the request is being forwarded, and an `X-Forwarded-Host` header is generated with the original `Host` value to allow the server to determine the original host the request was intended for. (We have always examined the `X-Forwarded-Proto` header; as of Diactoros 2.11.1, we also examine the `X-Forwarded-Port` header.) To accommodate this use case, we created Laminas\\Diactoros\\ServerRequestFilter\\FilterUsingXForwardedHeaders.\n\nDue to potential security issues, it is generally best to only accept these headers if you trust the reverse proxy that has initiated the request.\n(This value is found in `$_SERVER['REMOTE_ADDR']`, which is present as `$request-\u003egetServerParams()['REMOTE_ADDR']` within PSR-7 implementations.) `FilterUsingXForwardedHeaders` provides named constructors to allow you to trust these headers from any source (which has been the default behavior of Diactoros since the beginning), or to specify specific IP addresses or CIDR subnets to trust, along with which headers are trusted.\n\n`Laminas\\Diactoros\\ServerRequestFactory::fromGlobals()` was updated to accept a `FilterServerRequestInterface` as an additional, optional argument. Since the `X-Forwarded-*` headers do have valid use cases, particularly in clustered environments using a load balancer, to prevent backwards compatibility breaks, if no filter is provided, we generate an instance via `FilterUsingXForwardedHeaders::trustReservedSubnets()`, which generates an instance marked to trust only proxies on private subnets.\n\n### Workarounds\n\nInfrastructure or DevOps can configure web servers to reject `X-Forwarded-*` headers at the web server level.\n\nUsers of laminas/laminas-diactoros can make use of the `Laminas\\Diactoros\\RequestFilter\\RequestFilterInterface` functionality in order to either (a) disable usage of the `X-Forwarded-*` headers entirely, (b) opt-in to it, or (c) opt-in to the usage for configured proxy servers.\n\n### References\n\n- [HTTP Host Header Attacks](https://portswigger.net/web-security/host-header)\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Open an issue in [laminas/laminas-diactoros](https://github.com/laminas/laminas-diactoros/)\n- [Email us](mailto:security@getlaminas.org)","status":"published","published":"2022-07-27T22:05:18Z","modified":"2023-01-30T05:01:00Z","cvss":[{"version":"3.1","score":6.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium"}],"cwes":["CWE-79"],"updated_at":"2026-11-02T14:36:27.500048Z"}],"nvd":[{"id":"CVE-2022-31109","description":"laminas-diactoros is a PHP package containing implementations of the PSR-7 HTTP message interfaces and PSR-17 HTTP message factory interfaces.
