apostrophecms apostrophe

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.

ApostropheCMS 是一个开源的 Node.js 内容管理系统。在 4.34.0 版本之前，向接口发送请求体会返回一个布尔值，用于指示该 slug 是否在所有文档类型和可见性级别中被占用，且该接口未进行任何权限或类型过滤。因此，任何已登录的用户（包括编辑角色）均可枚举私有页面、草稿内容及已归档内容中的 slug 空间。该问题已在 4.34.0 版本中修复。
