ApostropheCMS: Exposure of Sensitive Information via predictable export filenames

Published Oct 20, 2026 · Updated Oct 20, 2026 · Assigned by GitHub_M

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.
