 ## [Unreleased]
 ## [0.3.6] - 2026-01-23
 ### Security
 - Added CSRF protection (nonce verification) to CSV export functionality
 - Fixed IP header spoofing vulnerability in rate limiting - now requires explicit trusted proxy configuration
 - Enabled explicit Twig autoescape for XSS protection
 - Fixed unescaped status values in CSS classes in Twig templates
 ### Fixed
 - Fixed response signing to use recursive key sorting for client compatibility
 - ResponseSigner now recursively sorts nested array keys alphabetically as required by client implementation
 ### Changed
 - Rate limiting now only trusts proxy headers when `WC_LICENSE_TRUSTED_PROXIES` constant is defined
 - Added Cloudflare IP range support via `WC_LICENSE_TRUSTED_PROXIES = 'CLOUDFLARE'` configuration
 - Improved IP detection with CIDR notation support for trusted proxy ranges
 ### Technical Details
 - Added `recursiveKeySort()` method to `ResponseSigner` for proper response signing
 - Added `isTrustedProxy()`, `isCloudflareIp()`, and `ipMatchesCidr()` methods to `RestApiController`
 - Twig environment now explicitly sets `autoescape => 'html'`
 - Export CSV link now includes nonce via `wp_nonce_url()`
 - Added `export_csv_url()` Twig function for generating export URL with nonce

 ## Security
 The plugin implements several security best practices:
 - **Input Sanitization**: All user inputs are sanitized using WordPress functions
 - **Output Escaping**: All output is escaped to prevent XSS attacks
 - **CSRF Protection**: Nonce verification on all forms and AJAX requests
 - **SQL Injection Prevention**: All database queries use prepared statements
 - **Capability Checks**: Admin functions require `manage_woocommerce` capability
 - **Secure Downloads**: File downloads use hash-verified URLs with user authentication
 - **Response Signing**: Optional HMAC-SHA256 signatures for API tamper protection
 ### Trusted Proxy Configuration
 If your server is behind a load balancer, reverse proxy, or CDN (like Cloudflare), you need to configure trusted proxies for accurate rate limiting. Without this, the rate limiter uses the direct connection IP which may be your proxy's IP.
 **Configuration (wp-config.php):**
 ```php
 // For Cloudflare (includes all Cloudflare IP ranges)
 define('WC_LICENSE_TRUSTED_PROXIES', 'CLOUDFLARE');
 // For specific proxy IPs
 define('WC_LICENSE_TRUSTED_PROXIES', '10.0.0.1,10.0.0.2');
 // For CIDR ranges
 define('WC_LICENSE_TRUSTED_PROXIES', '10.0.0.0/8,192.168.1.0/24');
 // Combine multiple methods
 define('WC_LICENSE_TRUSTED_PROXIES', 'CLOUDFLARE,10.0.0.1');
 ```
 **Note**: Only configure trusted proxies if you actually use them. Without this configuration, rate limiting is more secure against IP spoofing attacks.
