CVE-2026-112954— ApostropheCMS: Unauthenticated publicApiProjection bypass via search and sort query builders in the public REST API

Quick assessment

Affected

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，一种使用的公开 REST API 类型，会通过搜索成员资格和排序顺序预言机（oracles）暴露被排除的可搜索或可排序字段的信息。返回的字段仍受投影（projection）过滤，因此该漏洞允许攻击者对隐藏值进行针对性推断，而非无限制地泄露所有字段。此问题已在 4.34.0 版本中修复。

Vulnerability Title

ApostropheCMS: Unauthenticated publicApiProjection bypass via search and sort query builders in the public REST API

Source: CVE Program / CVE List V5

Vulnerability Description

ApostropheCMS is an open-source Node.js content management system. Prior to 4.34.0, a public REST API type that uses publicApiProjection can expose excluded searchable or sortable field information through search membership and sort ordering oracles. Returned fields remain filtered by the projection, so the issue permits targeted inference about hidden values rather than an unrestricted field dump. This issue is fixed in version 4.34.0.
