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 wpssfwinstallpluginconfiguration AJAX handler. This makes it possible for authenticated attackers, with shop manager-level access and above, to install and activate arbitrary WordPress.org plugins.

The Subscriptions for WooCommerce WordPress plugin before 2.0.1 does not verify that the requester owns the subscription being viewed before rendering its details, allowing any authenticated customer to read another customer's subscription information (the subscribed product, status, and dates) by supplying that subscription's ID.
