What is CVE-2026-112355?
CVE-2026-112355 is a high-severity vulnerability in MembershipWorks, published on 27 Oct 2026.
Official description
The MembershipWorks plugin for WordPress before 6.17 contains an information disclosure vulnerability that allows unauthenticated attackers to access member-only content through the WordPress REST API. Because the filter that strips protected content for non-members is only attached during normal front-end request handling and not during REST API requests, an unauthenticated attacker can retrieve the raw member-only content in a post or page’s rendered content, bypassing the plugin’s content protection.
