GHSA-f6p5-76fp-m248 URL Rewrite vulnerability in multiple zendframework components

• Packagist zendframework/zend-diactoros: < 1.8.4 → fixed in 1.8.4 • Packagist zendframework/zend-feed: < 2.10.3 → fixed in 2.10.3 • Packagist zendframework/zend-http: < 2.8.1 → fixed in 2.8.1

zend-diactoros (and, by extension, Expressive), zend-http (and, by extension, Zend Framework MVC projects), and zend-feed (specifically, its PubSubHubbub sub-component) each contain a potential URL rewrite exploit. In each case, marshaling a request URI includes logic that introspects 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 logic would still trigger, allowing a malicious client or proxy to emulate the headers to request arbitrary content.
