Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from using trustProxyData() which automatically trusts the immediate proxy (REMOTE_ADDR) without validation. When combined with getClientIp(), this allows attackers to spoof X-Forwarded-For headers if the application isn't behind a properly configured trusted proxy. The security patches replace trustProxyData() with setTrustedProxies() requiring explicit proxy IPs, confirming these functions' role in the vulnerability.
