## Description

The Subscriptions for WooCommerce with Stripe Recurring Payments plugin for WordPress is vulnerable to unauthorized plugin installation and activation in all versions up to, and including, 2.5.1, due to a missing capability check and missing nonce validation on the install_woocommerce_plugin() and wps_subscription_activate_woocommerce_plugin() AJAX functions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate the WooCommerce plugin on the site.
