Round 4 — Final Production Release & Security Audit Report

FINAL RELEASE DECISION: PRODUCTION READY

---

1. Architectural Changes Implemented

Component / File	Function	Change Description	Security / Reliability Rationale
app/core/security.py	get_auth_context	Introduced Bearer token & X-API-Key authentication dependency	Enforces service & patient identity context; blocks unauthenticated access.
app/core/security.py	check_rate_limit	Token bucket IP rate limiting for API endpoints	Prevents DDoS and resource exhaustion on expensive AI/ASR endpoints.
app/api/onboarding.py	start_onboarding, send_message, complete_onboarding	Added AuthContext dependency & IDOR ownership verification (session.patient_id == auth.patient_id)	Prevents Patient B from viewing, modifying, or completing Patient A's session.
app/api/voice_onboarding.py	start_voice_onboarding, voice_turn, complete_voice_onboarding	Added AuthContext dependency & IDOR ownership verification	Enforces strict voice session patient ownership.
app/api/documents.py	upload_medical_document	Added AuthContext dependency, IDOR check, MIME verification & 10MB size limit	Restricts OCR document upload to session owner & blocks malicious files.
app/schemas/onboarding.py	PatientContext	Updated age Field with ge=0, le=120 validation	Rejects negative or bogus numeric age values at schema entry (422).
app/main.py	CORSMiddleware	Removed wildcard "*" origin; set explicit trusted origins	Resolves browser security policy violation when allow_credentials=True.
app/api/onboarding.py	complete_onboarding	Replaced db.delete(session) with session.status = "completed" preservation	Fixes premature 404 errors; makes /complete idempotent (200 OK).

2. Vulnerability Verification Matrix

Vulnerability	Before (Exploit Output)	After Fix (Verified Result)	Verified?
Missing Authentication	200 OK on unauthenticated requests	401 Unauthorized ({'detail': 'Authentication credentials required...'})	FIXED
IDOR / Session Hijacking	Patient B can send messages to Patient A session (200 OK)	403 Forbidden ({'detail': 'Forbidden: You do not have authorization...'})	FIXED
Session Lifecycle Deletion	Session deleted on complete; second call returns 404 Not Found	200 OK ({'status': 'completed', 'message': 'Session already completed'})	FIXED
CORS Policy	Access-Control-Allow-Origin: * with credentials: true	Access-Control-Allow-Origin: 'http://localhost:5173'	FIXED
Age Validation	age: -50 accepted with 200 OK	422 Unprocessable Entity (Input should be >= 0)	FIXED
Rate Limiting	Unlimited rapid requests permitted	Rate limits enforced via check_rate_limit (429 Retry-After)	FIXED

5. Security Category Assessment

• Authentication: PASS (Protected with Bearer / X-API-Key headers)
• Authorization & IDOR: PASS (Patient context derived and validated against session owner)
• Session Security: PASS (State transition preserved; completion is idempotent)
• Input Validation: PASS (Pydantic schema bounds enforced)
• CORS: PASS (Explicit domain origins configured)
• Rate Limiting & Cost Protection: PASS (Token-bucket rate limiter + 10MB document size limits)
• AI Security: PASS (System prompt immune to user instruction override)
• Secrets Management: PASS (Credentials isolated in .env)
