description

Subscriptions for WooCommerce versions before 2.1.1 may expose membership-restricted WordPress posts and pages. An unauthenticated attacker can read restricted content when it is rendered through routes outside standard front-end page views.

mitigation

Update Subscriptions for WooCommerce to version 2.1.1 or later. Until updated, limit public access to alternate content-rendering routes where feasible.

fixed in 2.1.1
