    HTTP Request Smuggling

    h2 is a Pure-Python HTTP/2 protocol implementation

    Affected versions of this package are vulnerable to HTTP Request Smuggling via the processing of HTTP/2 request headers containing multiple Host headers. An attacker can interfere with downstream HTTP/1.1 applications by crafting requests that result in multiple Host headers being forwarded, potentially enabling request smuggling attacks.

    How to fix HTTP Request Smuggling?

    Upgrade h2 to version 4.4.1 or higher.
