Official description

The Membership Plugin – Restrict Content plugin for WordPress is vulnerable to Missing Authentication in all versions up to, and including, 3.2.16 via the 'rcp_stripe_create_setup_intent_for_saved_card' function due to missing capability check. Additionally, the plugin does not check a user-controlled key, which makes it possible for unauthenticated attackers to leak Stripe SetupIntent client_secret values for any membership.

The underlying weakness: Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How developers prevent this class of flaw

  • For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
