ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.0 of the import-export module, an authenticated user with import access to a target type can supply an object or operator as an update-key value, causing the import query to match an unidentified existing document that the user has generic edit permission to modify. The normal findForEditing permission filter still limits the candidate documents, so the issue does not permit permission-free overwrite of arbitrary protected content. This issue is fixed in version 3.7.0.
