CVE-2023-29406 is an HTTP request/header injection vulnerability in Go's net/http HTTP/1 client. The client insufficiently validates the contents of Request.Host and Request.URL.Host before serializing an outbound HTTP request. An attacker-controlled Host value containing invalid characters, including CRLF sequences, can inject additional HTTP headers or entire HTTP requests. Fixed Go versions reject requests with invalid Request.Host or Request.URL.Host values.
