zendframework/zendframework
source listedECOSYSTEM: introduced 2.2.0; fixed 2.2.5
The `Zend\Http\PhpEnvironment\RemoteAddress` class provides features around detecting the internet protocol (IP) address for an incoming proxied request via the X-Forwarded-For header, taking into account a provided list of trusted proxy server IPs. Prior to 2.2.5, the class was not taking into account whether or not the IP address contained in PHP's `$_SERVER['REMOTE_ADDR']` was in the trusted proxy server list. The IETF draft specification indicates that if `$_SERVER['REMOTE_ADDR']` is not a trusted proxy, it must be considered the originating IP address, and the value of X-Forwarded-For must be disregarded.

What to do next
- vendor patch
The original advisory lists fixed boundaries 2.2.5 for zendframework/zendframework. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
