description

MembershipWorks versions before 6.17 can expose member-only post or page content through the WordPress REST API. An unauthenticated remote attacker may read protected content when it is available in affected rendered pages or posts.

mitigation

Upgrade MembershipWorks to version 6.17 or later. Until upgraded, restrict unauthenticated access to the WordPress REST API where operationally feasible.
