If genuine, assess real-world severity strictly by impact, using this rubric: critical = remote code execution, full authentication bypass, or direct loss of funds/complete data compromise with no user interaction; high = significant data exposure, privilege escalation, or a serious integrity break requiring some precondition; medium = a real but bounded issue (e.g. limited information disclosure, a DoS requiring unusual conditions); low = a genuine but minor/hardening-class issue with negligible practical impact. If the claim does not hold up against the live content at all, is_real is false and severity is "none". 4. Report your own honest confidence in this verdict.
