Quick assessment

Affected
MembershipWorks MembershipWorks
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的 MembershipWorks 插件在 6.17 版本之前存在信息泄露漏洞，允许未认证的攻击者通过 WordPress REST API 访问仅限会员查看的内容。由于用于移除非会员可访问受保护内容的过滤器仅在前端常规请求处理时生效，而未在 REST API 请求期间应用，未认证的攻击者能够从帖子或页面的渲染内容中提取原始的会员专属内容，从而绕过该插件的内容保护机制。

Vulnerability Title
MembershipWorks WordPress Plugin < 6.17 Information Disclosure via WordPress REST API
Source: CVE Program / CVE List V5
Vulnerability 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.
