⚠️ Risk & Real-World Impact
Worst Case
Attackers could mark fraudulent orders as paid, causing financial loss and inventory issues, or mark legitimate orders as failed/refunded, disrupting business operations and customer trust.
Likely Case
Attackers manipulate order statuses to mark fraudulent orders as paid, leading to financial loss and inventory discrepancies.
If Mitigated
With proper IP allowlist validation and authorization checks, only legitimate BlueSnap IPN requests would be processed, preventing unauthorized order manipulation.
🎯 Exploit Status
Exploitation requires spoofing HTTP headers (X-Real-IP, X-Forwarded-For) to bypass IP allowlist validation, which is straightforward with common web testing tools.
