NVD Description

Note: Versions mentioned in the description apply only to the upstream falco package and not the falco package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value.
