Security Recommendations - HE2.AI Security Audit

These actions must be taken immediately to address critical security vulnerabilities that pose severe risks to the platform and user data.

Enable JWT Signature Verification
Replace all instances of disabled signature verification with proper validation:

# In backend/utils/auth_utils.py and backend/user_profiles/api.py payload = jwt.decode( token, config.SUPABASE_JWT_SECRET, algorithms=["HS256"], options={"verify_signature": True} )

Impact: Prevents authentication bypass and token forgery
Revoke Exposed GitHub Token
Immediately revoke the exposed token and generate a new one with minimal permissions. Scan codebase for other exposed secrets.

Impact: Prevents unauthorized repository access and code tampering
Implement Security Headers
Add comprehensive security headers middleware to protect against XSS, clickjacking, and other client-side attacks.

# In backend/api.py @app.middleware("http") async def add_security_headers(request: Request, call_next): response = await call_next(request) response.headers["X-Frame-Options"] = "DENY" response.headers["X-Content-Type-Options"] = "nosniff" response.headers["Strict-Transport-Security"] = "max-age=31536000" response.headers["Content-Security-Policy"] = "default-src 'self'" return response

Impact: Protects against XSS, clickjacking, and MITM attacks

Address high-priority security issues that significantly improve the security posture of the application.

Implement Comprehensive Rate Limiting
Add rate limiting to all API endpoints, especially authentication and resource-intensive operations.

from slowapi import Limiter from slowapi.util import get_remote_address limiter = Limiter(key_func=get_remote_address) app.state.limiter = limiter @app.post("/api/auth/login") @limiter.limit("5/minute") async def login(request: Request): # Login logic
Restrict CORS Configuration
Tighten CORS policies to only allow specific trusted origins instead of wildcard patterns.
Implement File Upload Validation
Add comprehensive validation for file uploads including type checking, size limits, and malware scanning.
Enhance Session Management
Implement proper session timeout, idle timeout, and session invalidation mechanisms.
Add CSRF Protection
Implement CSRF tokens for all state-changing operations.

Strengthen overall security posture with comprehensive improvements and monitoring.

Implement Security Monitoring & Alerting
Set up comprehensive logging, monitoring, and alerting for security events.
Conduct Dependency Audit
Review and update all dependencies, removing unused packages and updating vulnerable ones.
Implement API Versioning
Add proper API versioning to allow for security updates without breaking changes.
Enhance Password Policies
Implement stronger password requirements and consider adding multi-factor authentication.
Add Security Testing to CI/CD
Integrate automated security scanning tools into the deployment pipeline.

Establish ongoing security practices and continuous improvement processes.

Establish Security Review Process
Implement regular security code reviews and penetration testing schedules.
Create Security Documentation
Document security architecture, threat models, and incident response procedures.
Implement Bug Bounty Program
Consider launching a responsible disclosure program to engage security researchers.
Security Training
Provide regular security training for development team on secure coding practices.
Compliance & Certifications
Work towards relevant security certifications (SOC 2, ISO 27001) as the platform scales.
