Hi, The following vulnerability was published for twisted. CVE-2022-24801[0]: | Twisted is an event-based framework for internet applications, | supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web | HTTP 1.1 server, located in the `twisted.web.http` module, parsed | several HTTP request constructs more leniently than permitted by RFC | 7230. This non-conformant parsing can lead to desync if requests pass | through multiple HTTP parsers, potentially resulting in HTTP request | smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server | and/or proxy and also pass requests through a different HTTP server | and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 | server uses a different parser, so it is not affected. The issue has | been addressed in Twisted 22.4.0rc1. Two workarounds are available: | Ensure any vulnerabilities in upstream proxies have been addressed, | such as by upgrading them; or filter malformed requests by other | means, such as configuration of an upstream proxy. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
