      <title>CVE-2022-24790 — HTTP Request Smuggling in puma</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-24790</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; puma&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
