SSRF in N/a

CVE-2026-51152

Server-side request forgery (SSRF) in the /har/test endpoint in QD 20220208 through 20250803. Fetcher.build_request() in libs/fetcher.py constructs an httpclient.HTTPRequest from user-supplied JSON without validating URL scheme, host, or IP range. The /har/test handler does not require authentication, enabling unauthenticated remote attackers to force the QD server to send arbitrary HTTP requests to internal network resources and cloud metadata endpoints. validate_cert is set to False, disabling TLS verification.
