Paid Membership Subscriptions – Effortless Memberships, Recurring Payments & Content Restriction <= 3.0.9 - Unauthenticated Unauthorized Subscription Activation
The Paid Membership Subscriptions – Effortless Memberships, Recurring Payments & Content Restriction plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.0.9. This is due to missing server-side token validation on the Stripe SCA resume AJAX endpoint, allowing any request that supplied a valid payment intent ID to drive the handler against arbitrary member subscriptions. This makes it possible for unauthenticated attackers to complete another member's Stripe SCA authentication flow using only a known payment intent ID, activating or altering a subscription without authorization.
