How to fix?
Upgrade zendframework/zend-diactoros to version 1.8.4 or higher.
Overview
zendframework/zend-diactoros contains implementations of the accepted PSR-7 HTTP message interfaces, as well as a "server" implementation similar to node's http.Server.
Affected versions of this package are vulnerable to an Arbitrary URL Rewrite vulnerability. The request URI marshaling process contains logic that inspects HTTP request headers that are specific to a given server-side URL rewrite mechanism.
When these headers are present on systems not running the specific URL rewriting mechanism, the URLs are subject to rewriting, allowing a malicious client or proxy to emulate the headers to request arbitrary content.
