How to fix?

Upgrade iodine to version 0.7.39 or higher.

Overview

iodine is a fast HTTP / Websocket Server with built-in Pub/Sub support (with or without Redis), static file support and many other features, optimized for Ruby MRI on Linux / BSD / macOS.

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