"Twisted developers reports :

All HTTP clients in twisted.web.client now raise a ValueError when
called with a method and/or URL that contain invalid characters. This
mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this
vulnerability.

The HTTP/2 server implementation now enforces TCP flow control on
control frame messages and times out clients that send invalid data
without reading responses. This closes CVE-2019-9512 (Ping Flood),
CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood).
Thanks to Jonathan Looney and Piotr Sikora.

twisted.web.http was subject to several request smuggling attacks.
Requests with multiple Content-Length headers were allowed
(CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu
for reporting this) and now fail with a 400; requests with a
Content-Length header and a Transfer-Encoding header honored the first
header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for
reporting this) and now fail with a 400; requests whose
Transfer-Encoding header had a value other than 'chunked' and
'identity' (thanks to ZeddYu Lu) were allowed and now fail with a 400.");
