ApostropheCMS: Archive duplicate continuation lets contributors overwrite published content

Assigner: GitHub_M
Reserved: 19.10.2026 Published: 20.10.2026 Updated: 20.10.2026

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, duplicate-import continuation accepts client-controlled replacement choices without binding them to a user-owned server-side analysis or authorizing the canonical target. On an import-enabled localized type, a contributor with draft editing authority can cross the publication boundary by selecting a published document for replacement, although the current assessment is based on remediation review rather than a repeated end-to-end reproduction. This issue is fixed in version 3.7.1.
