CVE-2026-113664— ApostropheCMS import-export tar guard misses './..' because it is a literal '../' substring test

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 是一个开源的基于 Node.js 的内容管理系统。在导入导出模块的 3.7.0 版本之前，已认证的导入用户可以提交一个 tar 条目，其规范化后的目标路径指向某个目录，从而绕过对字面父路径子串的防护检查。将该目录作为写入流打开时，会触发一个未处理的文件系统错误，进而导致 Node.js 进程终止。该漏洞仅证实了此静态原语的存在，并未形成端到端的利用链，也无法实现受控的任意文件读取或写入。此问题已在 3.7.0 版本中修复。

Vulnerability Title
ApostropheCMS import-export tar guard misses './..' because it is a literal '../' substring test
Source: CVE Program / CVE List V5
Vulnerability Description
ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.0 of the import-export module, an authenticated importer can submit a tar entry whose normalized destination targets a directory while bypassing the literal parent-path substring guard. Opening that directory as a write stream emits an unhandled filesystem error that can terminate the Node.js process; the source establishes this static primitive but not an end-to-end exploit or controlled arbitrary file read or write. This issue is fixed in version 3.7.0.
