New CWE-200 Open this link in a new tab

How to fix?

Upgrade zendframework/zend-http to version 2.8.1 or higher.


Affected versions of this package are vulnerable to Information Exposure. 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.
