Upgrade the Membership Plugin to version 4.0.6 or later, where this authorization bypass vulnerability is fixed. No other mitigation is required once the plugin is updated.
Description
A vulnerability in the Membership Plugin for WordPress before version 4.0.6 allows subscriber-level users to bypass authorization checks. This flaw enables them to access another member's Stripe payment client secret and attach a payment method to that member's pending payment. The issue arises because the plugin does not verify that the membership referenced in a saved-card payment request belongs to the user making the request.
