The Paid Membership Subscriptions – Effortless Memberships, Recurring Payments & Content Restriction plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the creating_pricing_table_page function in all versions up to, and including, 2.11.1. This makes it possible for authenticated attackers, with subscriber access or higher, to create pricing tables.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
