## Detailed Code Changes
|
||||
|
||||
### Critical Fix #1: Sanitize AJAX Save Data
|
||||
|
||||
**File**: `class-wpfmj-admin.php`
|
||||
|
||||
**Before:**
|
||||
```php
|
||||
$config = array(
|
||||
'form_id' => intval($data['form_id']),
|
||||
'field_mapping' => $data['field_mapping'], // ❌ Direct use
|
||||
'trigger_field_id' => $data['trigger_field_id'], // ❌ Direct use
|
||||
'list_mappings' => $data['list_mappings'], // ❌ Direct use
|
||||
);
|
||||
```
|
||||
|
||||
**After:**
|
||||
```php
|
||||
// Validate field_mapping structure
|
||||
if (!is_array($data['field_mapping']) || !isset($data['field_mapping']['email'])) {
|
||||
wp_send_json_error('Invalid field mapping structure');
|
||||
}
|
||||
|
||||
$field_mapping = array(
|
||||
'email' => sanitize_text_field($data['field_mapping']['email']),
|
||||
'firstname' => isset($data['field_mapping']['firstname']) ? sanitize_text_field($data['field_mapping']['firstname']) : '',
|
||||
'lastname' => isset($data['field_mapping']['lastname']) ? sanitize_text_field($data['field_mapping']['lastname']) : '',
|
||||
);
|
||||
|
||||
// Validate and sanitize list_mappings
|
||||
if (!is_array($data['list_mappings'])) {
|
||||
wp_send_json_error('Invalid list mappings structure');
|
||||
}
|
||||
|
||||
$list_mappings = array();
|
||||
foreach ($data['list_mappings'] as $key => $value) {
|
||||
$list_mappings[sanitize_text_field($key)] = sanitize_text_field($value);
|
||||
}
|
||||
|
||||
$config = array(
|
||||
'form_id' => intval($data['form_id']),
|
||||
'field_mapping' => $field_mapping,
|
||||
'trigger_field_id' => sanitize_text_field($data['trigger_field_id']),
|
||||
'list_mappings' => $list_mappings,
|
||||
);
|
||||
```
|
||||
|
||||

|
||||
|
||||
### Critical Fix #2: Escape Dashboard Output
|
||||
|
||||
**File**: `class-wpfmj-dashboard.php`
|
||||
|
||||
**Before:**
|
||||
```javascript
|
||||
html += '<td><strong>' + automation.title + '</strong></td>';
|
||||
html += '<td>' + automation.form_name + '</td>';
|
||||
```
|
||||
|
||||
**After:**
|
||||
```javascript
|
||||
// Escape data for safe HTML output
|
||||
var title = $('<div>').text(automation.title).html();
|
||||
var formName = $('<div>').text(automation.form_name).html();
|
||||
var automationId = parseInt(automation.id);
|
||||
|
||||
html += '<td><strong>' + title + '</strong></td>';
|
||||
html += '<td>' + formName + '</td>';
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### High Priority Fix #3: API Rate Limiting
|
||||
|
||||
**File**: `class-wpfmj-mailjet-api.php`
|
||||
|
||||
**Before:**
|
||||
```php
|
||||
private function request($method, $endpoint, $data = array()) {
|
||||
$url = $this->api_url . $endpoint;
|
||||
// ... direct request
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```php
|
||||
private function request($method, $endpoint, $data = array()) {
|
||||
// Rate limiting: max 60 requests per minute
|
||||
$rate_limit_key = 'wpfmj_api_rate_' . md5($this->api_key);
|
||||
$requests = get_transient($rate_limit_key);
|
||||
|
||||
if ($requests === false) {
|
||||
$requests = 0;
|
||||
}
|
||||
|
||||
if ($requests >= 60) {
|
||||
return new WP_Error('rate_limit_exceeded', 'API rate limit exceeded. Please wait a moment and try again.');
|
||||
}
|
||||
|
||||
set_transient($rate_limit_key, $requests + 1, 60);
|
||||
|
||||
$url = $this->api_url . $endpoint;
|
||||
// ... rest of request
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
### High Priority Fix #4: Improved Decryption
|
||||
|
||||
**File**: `class-wpfmj-encryption.php`
|
||||
|
||||
**Before:**
|
||||
```php
|
||||
public static function decrypt($data) {
|
||||
try {
|
||||
// ... decryption
|
||||
return openssl_decrypt($encrypted, self::$method, $key, 0, $iv);
|
||||
} catch (Exception $e) {
|
||||
error_log('WPFMJ Decryption Error: ' . $e->getMessage());
|
||||
return ''; // ❌ Silent failure
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```php
|
||||
public static function decrypt($data) {
|
||||
try {
|
||||
// ... decryption with validation
|
||||
$decrypted = openssl_decrypt($encrypted, self::$method, $key, 0, $iv);
|
||||
|
||||
if ($decrypted === false) {
|
||||
error_log('WPFMJ Decryption Error: Decryption failed');
|
||||
return false; // ✅ Explicit failure
|
||||
}
|
||||
|
||||
return $decrypted;
|
||||
} catch (Exception $e) {
|
||||
error_log('WPFMJ Decryption Error: ' . $e->getMessage());
|
||||
return false; // ✅ Explicit failure
