Drupal 8 uses the third-party PHP library Guzzle for making server-side
HTTP requests. An attacker can provide a proxy server that Guzzle will
use. This vulnerability is called ‘httpoxy’. httpoxy is a set of
vulnerabilities that affect application code running in CGI, or CGI-like
environments. It comes down to a simple namespace conflict:

RFC 3875 (CGI) puts the HTTP Proxy header from a request into the
environment variables as HTTP_PROXY HTTP_PROXY is a popular environment
variable used to configure an outgoing proxy This leads to a remotely
exploitable vulnerability. If you’re running PHP or CGI, you should
block the Proxy header now.
