Hi,

The following vulnerability was published for puma.

CVE-2022-24790[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
