From fd039f61735ad11b3f3eb76274f01eb5e13a2071 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Thu, 30 Jul 2026 15:52:35 +0000 Subject: [PATCH 1/4] Fix CRLF header injection in CONNECT request Add RubyProxyHeaders.validate_header! to reject header names and values containing CR, LF, or NUL bytes before they are interpolated into raw HTTP CONNECT requests. This prevents HTTP request smuggling via the proxy when user-derived data flows into proxy_connect_request_headers. Applied in both net_http.rb (production code path) and connection.rb (standalone Connection class). Raises ArgumentError with a descriptive message so callers are alerted to the injection attempt rather than silently stripping characters.
