⚠️ Risk & Real-World Impact
Worst Case
Attackers could access internal services, exfiltrate sensitive data, or pivot to attack other internal systems from the compromised server.
Likely Case
Attackers could scan internal networks, access metadata services, or make requests to external systems while appearing to originate from the legitimate server.
If Mitigated
Limited impact if network segmentation restricts server outbound connections and internal services are properly firewalled.
🎯 Exploit Status
SSRF vulnerabilities typically have low exploitation complexity and may not require authentication depending on the specific implementation.
