Project: Tg_Pkr_Bot
Version: 1.0.0
Last Updated: January 14, 2026

This document outlines the security measures, potential vulnerabilities, and best practices for the Tg_Pkr_Bot project.

• Input Validation

  • All user inputs are validated before processing
  • Type checking via TypeScript
  • Validation middleware for API endpoints

• Rate Limiting

  • Rate limiting middleware implemented
  • Prevents DDoS attacks
  • Configurable limits per endpoint

• Authentication (Placeholder)

  • Auth middleware created (backend/src/middleware/auth.ts)
  • TODO: Implement JWT or session-based auth

• CORS Configuration

  • CORS properly configured
  • Whitelist specific origins in production

• Error Handling

  • Global error handler prevents sensitive info leakage
  • Errors logged but not exposed to client

• SQL Injection Prevention

  • Using parameterized queries
  • pg library with proper escaping

• Helmet.js

  • Security headers configured
  • XSS protection enabled

• XSS Prevention

  • React's built-in XSS protection
  • No dangerouslySetInnerHTML usage

• HTTPS Only (Production)

  • TODO: Enforce HTTPS in production
  • HTTP Strict Transport Security (HSTS)

• Content Security Policy

  • TODO: Implement CSP headers

• Dependency Scanning

  • Regular npm audit checks
  • Update vulnerable packages

• No Sensitive Data in Logs

  • Logger configured to exclude sensitive data
  • No passwords or tokens in logs

• Environment Variables

  • Secrets stored in .env (not in repo)
  • .env.example provided

• Database Security

  • Connection strings in env vars
  • Prepared statements for queries

Status: Not Fully Implemented
Risk: Low (application is client-side tool)
Action Required:

• If deploying as multi-user service, implement proper authentication
• Add JWT or OAuth2
• Implement user session management

Status: Basic Implementation
Risk: Low
Recommendation:

• Monitor rate limit effectiveness in production
• Adjust limits based on usage patterns
• Consider Redis-based rate limiting for distributed systems

Status: Basic
Risk: Medium
Action Required:

• Implement WebSocket authentication
• Add message validation
• Rate limit WebSocket connections

1. Never commit secrets

   # Always check before committing
   git diff --cached

2. Use environment variables

   // ❌ Bad
   const apiKey = 'abc123';
   
   // ✅ Good
   const apiKey = process.env.API_KEY;

3. Validate all inputs

   // ✅ Good
   if (!isValidCard(card)) {
     throw new Error('Invalid card');
   }

4. Sanitize user data

   // ✅ Good
   const sanitized = validator.escape(userInput);

1. Use HTTPS

   • Never deploy without SSL/TLS
   • Use Let's Encrypt for free certificates

2. Update dependencies regularly

   npm audit
   npm audit fix

3. Set proper CORS origins

   // ❌ Bad
   cors({ origin: '*' })
   
   // ✅ Good (production)
   cors({ origin: 'https://yourdomain.com' })

4. Enable security headers

   app.use(helmet({
     contentSecurityPolicy: true,
     hsts: true,
   }));

# NPM audit
npm audit

# Snyk (if installed)
snyk test

# OWASP Dependency Check
dependency-check --project Tg_Pkr_Bot --scan ./

• Code review for security issues
• Check for hardcoded secrets
• Review authentication logic
• Test input validation
• Check error messages for info leakage

1. Report: Open a private issue or email maintainers
2. Assess: Determine severity and impact
3. Patch: Develop and test fix
4. Deploy: Release security update
5. Notify: Inform users of the issue and update

• OWASP Top 10
• Node.js Security Checklist
• Express Security Best Practices

For security concerns, please contact:

• Create a private security advisory on GitHub
• Or open an issue with [SECURITY] prefix
