  "title": "python3-twisted: Twisted is an event-based framework for internet applications, supportingPython 3.6\u002B",
  "description": "Twisted is an event-based framework for internet applications, supportingPython 3.6\u002B. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server,located in the \u0060twisted.web.http\u0060 module, parsed several HTTP requestconstructs more leniently than permitted by RFC 7230. This non-conformantparsing can lead to desync if requests pass through multiple HTTP parsers,potentially resulting in HTTP request smuggling. Users who may be affecteduse Twisted Web\u0027s HTTP 1.1 server and/or proxy and also pass requeststhrough a different HTTP server and/or proxy. The Twisted Web client is notaffected. The HTTP 2.0 server uses a different parser, so it is notaffected. The issue has been addressed in Twisted 22.4.0rc1. Twoworkarounds are available: Ensure any vulnerabilities in upstream proxieshave been addressed, such as by upgrading them; or filter malformedrequests by other means, such as configuration of an upstream proxy.",
