### Official description

An unauthenticated attacker may perform a blind server side request forgery (SSRF), due to a CLRF injection issue that can be leveraged to perform HTTP request smuggling.

The attacker can control all the HTTP data sent in the SSRF connection, but the attacker can not receive any data back from this connection.
