What is CVE-2026-112355?

The MembershipWorks plugin for WordPress prior to version 6.17 contains a vulnerability that exposes member-only content via the WordPress REST API. This occurs because the mechanism to filter out protected content is only applied to front-end requests. Consequently, unauthenticated users can bypass security measures and access sensitive information intended for members, potentially leading to unauthorized disclosure of personal data.

Affected Version(s)

MembershipWorks 0 < 6.17
