CVE-2026-113649

MEDIUM 6.5

Published 2026-10-20 · Last modified 2026-10-23

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module and 4.34.0 of core ApostropheCMS, an editor who can import an enabled content type but lacks its stronger publication role can cause import write helpers to create, replace, or remove published variants without the normal publish permission and lifecycle checks. This issue is fixed in import-export 3.7.1 and ApostropheCMS 4.34.0.
