net/http: improper sanitization of Transfer-Encoding header
CVE: CVE-2022-1705
Component: golang
CWE: CWE-444
Severity: Moderate
CVSS v3: 6.4/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
Release date: 2022-07-12T00:00:00+00:00

A flaw was found in golang. The HTTP/1 client accepted invalid Transfer-Encoding headers indicating "chunked" encoding. This issue could allow request smuggling, but only if combined with an intermediate server that also improperly accepts the header as invalid.
