Description
The issue is related to HAProxy forwarding empty Content-Length headers, which violates RFC 9110 section 8.6. In uncommon cases, an HTTP/1 server behind HAProxy may interpret the payload as an extra request. This can be exploited by a remote attacker to perform an HTTP request smuggling attack.
