Overview
This PR addresses critical security vulnerabilities and implements comprehensive security hardening for the Laravel CRM system without modifying the core architecture. The changes ensure the application meets enterprise-level security standards while maintaining existing functionality.
Security Issues Addressed
🔴 Critical CORS Vulnerability
Problem: The CORS configuration was dangerously permissive, allowing any origin, header, and HTTP method:
Solution: Implemented restrictive CORS policy with specific allowed origins, headers, and methods:
🟡 Session Security Improvements
HttpOnly,Secure, andSameSite=strictflags🟡 Input Validation Enhancement
Before: Basic validation with potential for invalid data:
After: Strict validation with proper constraints:
🟡 API Security Hardening
New Security Features
Rate Limiting & Monitoring
Implemented
ApiSecurityMiddlewarethat provides:Authentication Enhancements
server_user_tokenin API responsesPerformance Optimizations
Added intelligent caching to external API calls:
This reduces external API calls and improves response times for frequently accessed data.
Testing & Documentation
Comprehensive Test Suite
Enhanced Documentation
Configuration Changes
Environment Variables
Added new security-focused environment variables:
Backward Compatibility
✅ All changes are backward compatible - no breaking changes to existing functionality
✅ Existing features remain unchanged - authentication, cart, orders work as before
✅ API contracts preserved - external integrations continue to work
✅ Database schema unchanged - no migrations required
Impact
Security Posture
Performance
Deployment Notes
For production deployment, ensure:
APP_ENV=productionandAPP_DEBUG=falseSERVER_API_URLwith HTTPS endpointSERVER_API_KEYfor external API authenticationSESSION_SECURE_COOKIE=truefor HTTPS environmentsThe system is now ready for secure production deployment with enterprise-level security measures.
