  "description": "Starman versions before 0.4018 for Perl allows HTTP Request Smuggling via Improper Header Precedence.  Starman incorrectly prioritizes \u0022Content-Length\u0022 over \u0022Transfer-Encoding: chunked\u0022 when both headers are present in an HTTP request. Per RFC 7230 3.3.3, Transfer-Encoding must take precedence.  An attacker could exploit this to smuggle malicious HTTP requests via a front-end reverse proxy.",
