Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends. This would allow requests to be smuggled via the front-end proxy to Puma. The vulnerability has been fixed in 5.6.4 and 4.3.12. Users are advised to upgrade as soon as possible. Workaround: when deploying a proxy in front of Puma, turning on any and all functionality to make sure that the request matches the RFC7230 standard.

When using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends. This would allow requests to be smuggled via the front-end proxy to Puma.
The following vulnerabilities are addressed by this advisory:
- Lenient parsing of `Transfer-Encoding` headers, when unsupported encodings should be rejected and the final encoding must be `chunked`.
- Lenient parsing of malformed `Content-Length` headers and chunk sizes, when only digits and hex digits should be allowed.
- Lenient parsing of duplicate `Content-Length` headers, when they should be rejected.
- Lenient parsing of the ending of chunked segments, when they should
