github.com/envoyproxy/envoy is vulnerable to Request Smuggling. The vulnerability is due to Envoy incorrectly accepting a 200 response code from a server when a protocol upgrade is requested, even though a 200 response does not indicate a protocol switch. Attackers could exploit this by tricking a server into adding an “Upgrade” header to a 200 response, potentially allowing request smuggling through Envoy.
