CVE-2023-29406
A maliciously crafted Host header can inject additional headers or entire requests.
MEDIUM 6.5EPSS 1.45%
Does this matter?
Lower severity and a low EPSS score (1.45%). Track it; it rarely justifies an emergency change on its own.
Description
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.
