Code injection in Happy Plugins Shortcodes AnyWhere 1.0.1 and earlier allows remote attackers to execute arbitrary shortcodes. The plugin passes an action-controlled value to WordPress's do_shortcode function without validating the value. No authentication or user interaction is required, and the resulting impact depends on the shortcode handlers available on the WordPress site.
