CVE-2022-21712: It was discovered that Twisted incorrectly filtered HTTP headers when clients are being redirected to another origin. A remote attacker could use this issue to obtain sensitive information. CVE-2022-21716: It was discovered that Twisted incorrectly processed SSH handshake data on connection establishments. A remote attacker could use this issue to cause Twisted to crash, resulting in a denial of service. GHSA-rv6r-3f5q-9rgx The Twisted SSH client and server implementation naively accepted an infinite amount of data for the peer’s SSH version identifier. GHSA-c2jg-hw38-jrqq and CVE-2022-24801 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 GHSA-92x2-jw7w-xvvx: twisted.web.client.getPage, twisted.web.client.downladPage, and the associated implementation classes (HTTPPageGetter, HTTPPageDownloader, HTTPClientFactory, HTTPDownloader) have been removed because they do not segregate cookies by domain. They were deprecated in Twisted 16.7.0 in favor of twisted.web.client.Agent.
