**Release Date**: 2025-10-09
**Version**: 1.3
**Previous Version**: 1.2

---

## 🎯 Release Highlights

Version 1.3 focuses on **security hardening**, **build optimization**, and **developer experience improvements** based on comprehensive code analysis and security audit.

### Key Improvements
- ✅ **Critical Security Fixes**: Resolved unsanitized input vulnerabilities
- ✅ **Production-Ready Builds**: Disabled source maps in production for security
- ✅ **Build System Enhancement**: Separate dev/prod build configurations
- ✅ **Developer Documentation**: Comprehensive build and improvement guides

---

## 🔒 Security Enhancements

### 1. Fixed Unsanitized POST Parameter Vulnerability
**Severity**: HIGH
**File**: `class-eventbookings-shortcode.php:373-378`

**Issue**: Direct use of `$_POST['eventUuid']` in API URL construction without sanitization could allow API parameter injection.

**Fix Applied**:
```php
// Before (Vulnerable)
$api_url = EVENTBOOKINGS_BASE_URL . '/events/' . $_POST['eventUuid'];

// After (Secured)
$event_uuid = isset($_POST['eventUuid']) ? sanitize_text_field(wp_unslash($_POST['eventUuid'])) : '';
if (empty($event_uuid)) {
    wp_send_json_error(['message' => 'Event UUID is required']);
    return;
}
$api_url = EVENTBOOKINGS_BASE_URL . '/events/' . $event_uuid;
```

**Impact**: Prevents malicious data injection into external API endpoints.

---

### 2. Added Missing wp_unslash() to GET Parameters
**Severity**: MEDIUM
**File**: `class-eventbookings-shortcode.php:163`

**Fix Applied**:
```php
// Before
if (isset($_GET['status']) && sanitize_text_field($_GET['status']) === 'success') {

// After
if (isset($_GET['status']) && sanitize_text_field(wp_unslash($_GET['status'])) === 'success') {
```

**Impact**: Ensures proper handling of slashed data in all edge cases, following WordPress best practices.

## 🚀 Build System Improvements

### 3. Conditional Source Maps (Production vs Development)
**File**: `webpack.config.js`

**Changes**:
- **Production builds**: Source maps disabled (`devtool: false`)
- **Development builds**: Source maps enabled (`devtool: 'source-map'`)
- **Environment detection**: Automatic via `NODE_ENV` environment variable

**Configuration**:
```javascript
const isDevelopment = process.env.NODE_ENV === 'development';

module.exports = {
  mode: isDevelopment ? 'development' : 'production',
  devtool: isDevelopment ? 'source-map' : false,
  watch: isDevelopment,
  // ... rest of config
};
```

**Benefits**:
- **Security**: Production builds don't expose source code structure
- **Performance**: Smaller deployment bundle (no .map files)
- **Developer Experience**: Full debugging support in development mode

---

### 4. New NPM Build Scripts
**File**: `package.json`

**Added Scripts**:
```json
{
  "scripts": {
    "build": "cross-env NODE_ENV=production webpack",
    "build:dev": "cross-env NODE_ENV=development webpack",
    "watch": "cross-env NODE_ENV=development webpack --watch"
  }
}
```

**Usage**:
- `npm run build` - Production build (minified, no source maps)
- `npm run build:dev` - Development build (unminified, with source maps)
- `npm run watch` - Development watch mode (auto-rebuild on file changes)

---

### 5. Cross-Platform Environment Variables
**New Dependency**: `cross-env`

Ensures `NODE_ENV` works correctly on Windows, Mac, and Linux.

## 🧪 Testing Recommendations

### Security Testing
```bash
# Test POST parameter sanitization
curl -X POST http://example.com/wp-admin/admin-ajax.php \
  -d "action=eventbookings_wp_get_event_details" \
  -d "ajax_nonce=<valid_nonce>" \
  -d "eventUuid=<script>alert('XSS')</script>"

# Expected: Sanitized UUID, no script execution
```

### Build Verification
```bash
# Check for source map URLs in production bundle
grep -i "sourceMappingURL" eventbookings/includes/js/dist/component-bundle.js

# Expected: No matches found
```

### Functional Testing
- [ ] Event listings display correctly
- [ ] Featured events carousel works
