Issue Overview:
A flaw was found in Varnish. This flaw allows an attacker to carry out a request smuggling attack on HTTP/1 connections on Varnish cache servers. This smuggled request goes through the usual Varnish Configuration Language (VCL) processing since the Varnish server treats it as an additional request. (CVE-2022-23959)
