SCA: security update for @apostrophecms/import-export (GHSA-mwxc-m426-3f78)

critical Tenable Self-Hosted Container Security Plugin ID 438997

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ApostropheCMS is an open-source content management framework. Prior to version 3.5.3 of
 `@apostrophecms/import-export`, The `extract()` function in `gzip.js` constructs file-write paths using
 `fs.createWriteStream(path.join(exportPath, header.name))`. `path.join()` does not resolve or sanitise
 traversal segments such as `../`. It concatenates them as-is, meaning a tar entry named `../../evil.js`
 resolves to a path outside the intended extraction directory. No canonical-path check is performed before
 the write stream is opened. This is a textbook Zip Slip vulnerability. Any user who has been granted the
 Global Content Modify permission — a role routinely assigned to content editors and site managers — can
 upload a crafted `.tar.gz` file through the standard CMS import UI and write attacker-controlled content
 to any path the Node.js process can reach on the host filesystem. Version 3.5.3 of `@apostrophecms/import-
 export` fixes the issue. (CVE-2026-32731)

Solution

Update the @apostrophecms/import-export library and its related packages to version 3.5.3 or later.
