CVE-2023-29406

CVE-2023-29406 · Insufficient sanitization of Host header in net/http

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
