Overview
@apostrophecms/import-export is an Import Export Documents for ApostropheCMS
Affected versions of this package are vulnerable to Information Exposure due to predictable filenames for publicly accessible export archives under /uploads/exports/. Filenames are generated from the site’s shortName, document type, timestamp, and format extension without a secret token. An unauthenticated attacker who guesses an archive’s URL can download it and access its contents while the file remains available. Export archives expire after 10 minutes by default, but this period can be extended through importExport.export.expiration.
