CVE-2026-112953— ApostropheCMS: Exposure of Sensitive Information via predictable export filenames

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 是一个基于 Node.js 的开源内容管理系统。在导入导出模块的 3.7.1 版本之前，由于导出的归档文件名具有可预测性，未认证的攻击者可在归档过期或被删除之前，从公开可读的导出存储中下载其他用户的导出文件。该漏洞利用的前提是：拥有导出权限的用户必须先创建归档；而对于已禁用导出功能、使用私有上传存储或要求认证才能交付上传内容的站点，则不会通过此网络下载路径受到暴露。该问题已在 3.7.1 版本中修复。

Vulnerability Title
ApostropheCMS: Exposure of Sensitive Information via predictable export filenames
Source: CVE Program / CVE List V5
Vulnerability Description
ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, predictable export archive filenames allow an unauthenticated requester to download another user's export from publicly readable export storage before the archive expires or is removed. A user with export permission must first create the archive, and sites with exports disabled, private upload storage, or authenticated upload delivery are not exposed through this network-download path. This issue is fixed in version 3.7.1.
