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.
