Overview

agoo is a fast HTTP server supporting rack.

Affected versions of this package are vulnerable to HTTP Request Smuggling. HTTP pipelining issues and request smuggling attacks might be possible due to incorrect Content-Length and Transfer encoding header parsing.

It is possible to conduct HTTP request smuggling attacks where agoo is used as part of a chain of backend servers due to insufficient Content-Length and Transfer Encoding parsing.
