Description Pedro Sampaio 2022-01-25 13:34:45 UTC

A request smuggling attack can be performed on HTTP/1 connections on Varnish Cache servers. The smuggled request would be treated as an additional request by the Varnish server, go through normal VCL processing, and injected as a spurious response on the client connection.
