No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Subscriptions for WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.0.0. This is due to the plugin not properly verifying that a user is authorized to perform an action via the wps_sfw_install_plugin_configuration AJAX handler. This makes it possible for authenticated attackers, with shop manager-level access and above, to install and activate arbitrary WordPress.org plugins.
