Descriptions

Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http before Go 1.17.12 and Go 1.18.4 allows HTTP request smuggling if combined with an intermediate server that also improperly fails to reject the header as invalid.

La aceptación de algunos encabezados Transfer-Encoding inválidas en el cliente HTTP/1 en net/http versiones anteriores a Go 1.17.12 y Go 1.18.4, permite un contrabando de peticiones HTTP si es combinado con un servidor intermedio que tampoco rechaza indebidamente el encabezado como no válido

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.
