Technical details

This is a path traversal (Zip Slip) vulnerability in the gzip extraction function (packages/import-export/lib/formats/gzip.js, lines ~132–157). The vulnerable code uses path.join(exportPath, header.name) to construct file write paths without sanitizing or canonicalizing traversal segments like "../". An attacker with Global Content Modify permission (a standard editor-level role) can craft a .tar.gz archive containing entries with traversal payload names (e.g., "../../evil.js") and upload it via the CMS import UI. The unsanitized paths allow writes outside the intended extraction directory, potentially reaching the public web directory, configuration files, or Node.js startup modules. This enables arbitrary file write, persistent backdoors on restart, credential theft, or denial of service. The vulnerability has been patched in version 3.5.3 of @apostrophecms/import-export.
