+# Security Audit Report
+
+**Date**: 2026-02-13  
+**Auditor**: Cascade AI  
+**Scope**: AITBC Platform Security Review  
+**Status**: ✅ All Critical Issues Resolved
+
+## Executive Summary
+
+A comprehensive security audit was conducted on the AITBC platform, identifying and resolving 5 critical security vulnerabilities. All issues have been fixed and deployed to production.
+
+## Findings & Remediation
+
+### 1. Hardcoded Secrets 🔴 Critical
+
+**Issue**: 
+- JWT secret hardcoded in `config_pg.py`
+- PostgreSQL credentials hardcoded in `db_pg.py`
+
+**Impact**: 
+- Authentication bypass possible
+- Database compromise risk
+
+**Remediation**:
+```python
+# Before
+jwt_secret: str = "change-me-in-production"
+
+# After
+jwt_secret: str = Field(..., env='JWT_SECRET')
+validate_secrets()  # Fail-fast if not provided
+```
+
+**Status**: ✅ Resolved
+
+### 2. Authentication Gaps 🔴 Critical
+
+**Issue**:
+- Exchange API endpoints without authentication
+- Hardcoded `user_id=1` in order creation
+
+**Impact**:
+- Unauthorized access to trading functions
+- Data exposure
+
+**Remediation**:
+```python
+# Added session-based authentication
+@app.post("/api/orders", response_model=OrderResponse)
+def create_order(
+    order: OrderCreate, 
+    db: Session = Depends(get_db_session),
+    user_id: UserDep  # Authenticated user
+):
+```
+
+**Status**: ✅ Resolved
+
+### 3. CORS Misconfiguration 🟡 High
+
+**Issue**:
+- Wildcard origins allowed (`allow_origins=["*"]`)
+
+**Impact**:
+- Cross-origin attacks from any website
+- CSRF vulnerabilities
+
+**Remediation**:
+```python
+# Before
+allow_origins=["*"]
+
+# After
+allow_origins=[
+    "http://localhost:3000",
+    "http://localhost:8080", 
+    "http://localhost:8000",
+    "http://localhost:8011"
+]
+```
+
+**Status**: ✅ Resolved
+
+### 4. Weak Encryption 🟡 High
+
+**Issue**:
+- Wallet private keys using weak XOR encryption
+- No key derivation
+
+**Impact**:
+- Private keys easily compromised
+- Wallet theft
+
+**Remediation**:
+```python
+# Before
+encrypted = xor_encrypt(private_key, password)
+
+# After
+encrypted = encrypt_value(private_key, password)  # Fernet
+# Uses PBKDF2 with SHA-256 for key derivation
+```
+
+**Status**: ✅ Resolved
+
+### 5. Database Session Inconsistency 🟡 Medium
+
+**Issue**:
+- Multiple session dependencies across routers
+- Legacy code paths
+
+**Impact**:
+- Potential connection leaks
+- Inconsistent transaction handling
+
+**Remediation**:
+- Migrated all routers to `storage.SessionDep`
+- Removed legacy `deps.get_session`
+
+**Status**: ✅ Resolved
+
+## Additional Improvements
+
+### CI/CD Security
+- Fixed import error causing build failures
+- Replaced `requests` with `httpx` (already a dependency)
+- Added graceful fallback for missing dependencies
+
+## Deployment
+
+### Site A (aitbc.bubuit.net)
+- All security fixes deployed and active
+- Services restarted and verified
+- CORS restrictions confirmed working
+
+### Site B (ns3)
+- No action needed
+- Only runs blockchain node (not affected)
+
+## Verification
+
+### Security Tests Passed
+- ✅ Unauthorized origins blocked (400 Bad Request)
+- ✅ Authentication required for protected endpoints
+- ✅ Wallet encryption/decryption functional
+- ✅ Secrets validation on startup
+- ✅ CI pipeline passes
+
+### Health Checks
+```bash
+# All services operational
+curl https://aitbc.bubuit.net/api/v1/health
+# {"status":"ok","env":"dev"}
+
+curl https://aitbc.bubuit.net/exchange/api/health
+# {"status": "ok", "database": "postgresql"}
+```
+
+## Recommendations
+
+### Short Term
+1. Set up automated security scanning in CI
+2. Implement secret rotation policies
+3. Add rate limiting to authentication endpoints
+
+### Long Term
+1. Implement OAuth2/JWT for all APIs
+2. Add comprehensive audit logging
+3. Set up security monitoring and alerting
+
+## Conclusion
+
+All critical security vulnerabilities have been resolved. The AITBC platform now follows security best practices with proper authentication, encryption, and access controls. Regular security audits should be conducted to maintain security posture.
+
+**Next Review**: 2026-05-13 (Quarterly)
