Privilege Escalation in ApostropheCMS Import-Export Module

Publication date: 2026-10-20

Last updated on: 2026-10-20

Assigner: GitHub, Inc.

Description
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.

Executive Summary

ApostropheCMS is a content management system. A flaw in versions before 3.7.1 of its import-export module allows contributors with draft editing rights to replace published content without proper authorization. The system fails to bind replacement choices to a user-owned server-side analysis, enabling unauthorized published-content modification.

Detection Guidance

Check the version of the ApostropheCMS import-export module. If it is below 3.7.1, the system is vulnerable. Use commands like npm list @apostrophecms/import-export to verify the installed version.

Impact Analysis

An attacker with contributor access could overwrite published content, potentially altering or deleting important information. This could lead to misinformation, data loss, or reputational damage if the content is critical to operations or public-facing.

Compliance Impact

This vulnerability could violate compliance requirements that mandate data integrity and access controls, such as GDPR's accuracy principle or HIPAA's integrity safeguards. Unauthorized content modification may lead to non-compliance penalties or legal consequences.

Mitigation Strategies

Upgrade the import-export module to version 3.7.1 or later immediately. Restrict contributor permissions to prevent unauthorized published content modifications until the update is applied.
