SQL Injection exists in the Google Map Landkarten through 4.2.3 component for Joomla! via the cid or id parameter in a layout=form_markers action, or the map parameter in a layout=default action.
In WordPress through 4.9.2, unauthenticated attackers can cause a denial of service (resource consumption) by using the large list of registered .js files (from wp-includes/script-loader.php) to construct a series of requests to load every file many times.
