Security

Kavro save actions should always use capability checks, nonces, and field-aware sanitization.

Recommended checks

• Verify nonces for AJAX and form requests.
• Check capabilities with current_user_can().
• Escape output with esc_html(), esc_attr(), esc_url(), or wp_kses_post().
• Sanitize all saved data.
• Prevent direct file access with defined( 'ABSPATH' ) || exit;.
