It does not primarily use the Access Token for these purposes (though the Access Token is available for templated headers if needed). Therefore, ensure that all necessary claims (e.g., email, roles, custom attributes) are included in the ID Token by your OIDC provider's configuration. -The middleware has been tested with Auth0, Logto, Google and other standard OIDC providers.

Examples](#provider-specific-configuration-examples) section. ## Recent Improvements -### Memory Management (v0.3.0+) +### Security Features (v0.4.0+) -The middleware has undergone significant improvements to memory management and resource utilization: +- **Security Headers**: Complete security headers system with CSP, HSTS, CORS, and XSS protection +- **Multiple Security Profiles**: Choose from default, strict, development, API, or custom security configurations +- **Enhanced Token Validation**: Improved JWT validation with comprehensive security checks +- **Advanced Rate Limiting**: Configurable rate limiting to prevent abuse -- **Memory Leak Prevention**: All background goroutines are properly managed with context cancellation -- **Bounded Resource Usage**: Session storage, metadata cache, and token cache all have size limits with LRU eviction -- **Automatic Cleanup**: Expired sessions and tokens are automatically cleaned up by background tasks -- **Graceful Shutdown**: All resources are properly released when the middleware is stopped -- **Performance Monitoring**: Built-in monitoring for goroutine leaks and memory growth +### User Experience (v0.4.0+) -These improvements ensure the middleware operates efficiently even under high load and long-running deployments. +- **Automatic Provider Detection**: Seamless configuration for major OIDC providers +- **Improved Error Handling**: Better error messages and graceful degradation +- **Enhanced Session Management**: More reliable session handling with automatic cleanup +- **Flexible Configuration**: Expanded configuration options for different deployment scenarios -### Enhanced Test Coverage +### Reliability (v0.4.0+) -- Comprehensive test suite with race condition detection -- Memory leak detection tests -- Goroutine leak prevention tests -- Test coverage increased to 67%+ for main package, 87-99% for subpackages +- **Automatic Token Refresh**: Proactive token refresh to prevent authentication interruptions +- **Memory Management**: Improved memory efficiency and automatic resource cleanup +- **Better Provider Support**: Enhanced compatibility with provider-specific features +- **Comprehensive Testing**: Extensive test coverage ensures reliability in production -## Architecture and Internal Improvements +## Architecture Overview -### Internal Components +### Design Principles -The middleware uses several internal components for efficient operation: +The middleware is designed with the following principles: -1. **SessionManager**: Manages user sessions with automatic cleanup and pool-based allocation -2. **ChunkManager**: Handles large session data by splitting it into manageable chunks -3. **MetadataCache**: Caches OIDC provider metadata with LRU eviction and size limits -4. **TaskRegistry**: Manages background tasks with proper lifecycle management -5. **MemoryMonitor**: Monitors memory usage and detects potential leaks +- **Reliability**: Automatic error recovery and graceful degradation +- **Security**: Comprehensive security measures and validation +- **Performance**: Efficient resource usage and caching +- **Flexibility**: Extensive configuration options for different use cases +- **Compatibility**: Support for all major OIDC providers with automatic detection -### Key Design Decisions +### Key Features -- **Context-based cancellation**: All background operations use context for clean shutdown -- **Bounded queues and caches**: Prevents unbounded memory growth -- **LRU eviction policies**: Ensures most frequently used data stays in cache -- **Atomic operations**: Uses atomic counters for statistics to avoid lock contention -- **Test-friendly design**: Special handling for test environments to ensure clean test execution +- **Automatic Session Management**: Handles session lifecycle, cleanup, and security +- **Provider Integration**: Seamless integration with OIDC providers including auto-discovery +- **Security Integration**: Built-in security headers and protection mechanisms +- **Resource Management**: Efficient memory usage and automatic cleanup +- **Error Handling**: Comprehensive error recovery and user-friendly error messages ## Contributing diff --git a/auth/auth_handler_test.go b/auth/auth_handler_test.go new file mode 100644 index 0000000..a2d6731 --- /dev/null +++

Troubleshooting + +### Common Issues + +1. **Invalid redirect URI** + - Ensure callback URL exactly matches provider configuration + - Check for HTTP vs HTTPS mismatches + +2. **Scope errors** + - Verify required scopes are configured in provider + - Some providers require specific scopes for refresh tokens + +3. **Token validation failures** + - Check provider URL format and accessibility + - Verify `.well-known/openid-configuration` endpoint is reachable + +4. **Session issues** + - Ensure session encryption key is properly configured + - Check cookie domain settings for subdomain scenarios + +### Debug Mode +Enable debug logging to troubleshoot configuration issues: +```yaml +logLevel: "debug" +``` + +This will provide detailed logs of the authentication flow and help identify configuration problems. + +--- + +## Security Headers Configuration + +The plugin includes comprehensive security headers support to protect your applications against common web vulnerabilities. + +### Default Security Headers + +By default, the plugin applies these security headers: + +- `X-Frame-Options: DENY` - Prevents clickjacking +- `X-Content-Type-Options: nosniff` - Prevents MIME sniffing +- `X-XSS-Protection: 1; mode=block` - Enables XSS protection +- `Referrer-Policy: strict-origin-when-cross-origin` - Controls referrer information +- `Strict-Transport-Security` - Forces HTTPS (when HTTPS is detected) + +### Security Profiles + +Choose from predefined security profiles or create custom configurations: + +#### Default Profile (Recommended) +```yaml +securityHeaders: + enabled: true + profile: "default" +``` + +#### Strict Profile (Maximum Security) +```yaml +securityHeaders: + enabled: true + profile: "strict" + # Additional strict CSP and cross-origin policies +``` + +#### Development Profile (Local Development) +```yaml +securityHeaders: + enabled: true + profile: "development" + # Relaxed policies for local development +``` + +#### API Profile (API Endpoints) +```yaml +securityHeaders: + enabled: true + profile: "api" + corsEnabled: true + corsAllowedOrigins: ["https://your-frontend.com"] +``` + +### Custom Security Configuration + +For complete control, use the custom profile: + +```yaml +securityHeaders: + enabled: true + profile: "custom" + + # Content Security Policy + contentSecurityPolicy: "default-src 'self'; script-src 'self' 'unsafe-inline'" + + # HSTS Configuration + strictTransportSecurity: true + strictTransportSecurityMaxAge: 31536000 # 1 year + strictTransportSecuritySubdomains: true + strictTransportSecurityPreload: true + + # Frame and content protection + frameOptions: "DENY" # or "SAMEORIGIN", "ALLOW-FROM uri" + contentTypeOptions: "nosniff" + xssProtection: "1; mode=block" + referrerPolicy: "strict-origin-when-cross-origin" + + # Permissions policy (feature policy) + permissionsPolicy: "geolocation=(), microphone=(), camera=()" + + # Cross-origin policies + crossOriginEmbedderPolicy: "require-corp" + crossOriginOpenerPolicy: "same-origin" + crossOriginResourcePolicy: "same-origin" + + # CORS configuration + corsEnabled: true + corsAllowedOrigins: + - "https://app.example.com" + - "https://*.api.example.com" + corsAllowedMethods: ["GET", "POST", "PUT", "DELETE", "OPTIONS"] + corsAllowedHeaders: ["Authorization", "Content-Type", "X-Requested-With"] + corsAllowCredentials: true + corsMaxAge: 86400 # 24 hours + + # Custom headers + customHeaders: + X-Custom-Header: "custom-value" + X-API-Version: "v1" + + # Server identification + disableServerHeader: true + disablePoweredByHeader: true +``` + +### Complete Example with Security Headers + +Here's a complete configuration example for Google OIDC with custom security headers: + +```yaml +# Traefik dynamic configuration +http: + middlewares: + secure-google-oidc: + plugin: + traefik-oidc: + # OIDC Configuration + providerUrl: "https://accounts.google.com" + clientId: "123456789-abcdef.apps.googleusercontent.com" + clientSecret: "GOCSPX-your-client-secret" + callbackUrl: "https://your-domain.com/auth/callback" + sessionEncryptionKey: "your-32-character-encryption-key-here" + + # Domain restrictions + allowedUserDomains: ["your-company.com"] + + # Security Headers + securityHeaders: + enabled: true + profile: "strict" + corsEnabled: true + corsAllowedOrigins: + - "https://your-frontend.com" + - "https://*.your-domain.com" + corsAllowCredentials: true + customHeaders: + X-Company: "YourCompany" + X-Environment: "production" + + routers: + secure-app: + rule: "Host(`your-domain.com`)" + middlewares: + - secure-google-oidc + service: your-app-service + tls: + certResolver: letsencrypt +``` + +### CORS Configuration Details + +For applications with frontend-backend separation, configure CORS properly: + +#### Simple CORS (Single Origin) +```yaml +securityHeaders: + corsEnabled: true + corsAllowedOrigins: ["https://app.example.com"] + corsAllowCredentials: true +``` + +#### Wildcard Subdomains +```yaml +securityHeaders: + corsEnabled: true + corsAllowedOrigins: ["https://*.example.com"] + corsAllowCredentials: true +``` + +#### Development with Multiple Ports +```yaml +securityHeaders: + profile: "development" + corsEnabled: true + corsAllowedOrigins: + - "http://localhost:*" + - "http://127.0.0.1:*" +``` + +### Security Best Practices + +1. **Always use HTTPS in production** + - Set `forceHttps: true` + - Configure proper TLS certificates + +2. **Implement proper CSP** + - Start with strict policy + - Add exceptions only when necessary + - Test thoroughly + +3. **Configure CORS restrictively** + - Only allow necessary origins + - Use specific domains instead of wildcards when possible + +4. **Enable HSTS** + - Use long max-age values (1 year minimum) + - Include subdomains when appropriate + +5. **Monitor security headers** + - Use browser developer tools to verify headers + - Test with security scanning tools + - Regularly review and update policies + +### Testing Security Headers + +Use browser developer tools or online tools to verify your security headers: + +1. **Browser DevTools**: Check Network tab → Response Headers +2. **Online scanners**: Use securityheaders.com or observatory.mozilla.org +3. **Command line**: Use `curl -I https://your-domain.com` + +Example verification: +```bash +curl -I https://your-domain.com +# Should show security headers in response +``` \ No newline at end of file diff --git
