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 是一个开源的基于 Node.js 的内容管理系统。在 db-connect 1.1.0 版本之前以及 ApostropheCMS 4.33.0 版本之前，拥有“查看草稿”（view-draft）权限的账户可以提交一个投影排除路径（projection exclusion path），该路径会遍历构造函数原型链，最终访问到共享的原型成员。此漏洞在消费者使用 SQLite、PostgreSQL 或 multipostgres 适配器，且存在匹配文档时触发。所有编辑角色默认均拥有“查看草稿”权

Vulnerability Title
ApostropheCMS: Authenticated projection-exclusion prototype-member deletion in @apostrophecms/db-connect causes process-wide denial of service
Source: CVE Program / CVE List V5
Vulnerability Description
ApostropheCMS is an open-source Node.js content management system. Prior to 1.1.0 of db-connect and 4.33.0 of ApostropheCMS, an account with view-draft access can submit a projection exclusion path that traverses through a constructor prototype chain to a shared prototype member when a consumer uses a SQLite, PostgreSQL, or multipostgres adapter and has a matching document. Every editing role has view-draft access, while guestApiAccess broadens this prerequisite to any logged-in account. The unsetNestedField helper then deletes the shared runtime member, causing persistent process-wide integrity and availability effects; the default MongoDB adapter is not affected. This issue is fixed in db-connect 1.1.0 and ApostropheCMS 4.33.0.
