Name of the Vulnerable Software and Affected Versions Go version 1.11.5

Description An issue was discovered in the net/http package of Go, where CRLF injection is possible if the attacker controls a url parameter. This is demonstrated by the second argument to http.NewRequest with r followed by an HTTP header or a Redis command.

Recommendations For Go version 1.11.5, consider restricting the use of the http.NewRequest function with user-controlled url parameters until a patch is available. As a temporary workaround, avoid using the http.NewRequest function with r followed by an HTTP header or a Redis command. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
