Description

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, ApostropheCMS’s exist-in-locale API allows an authenticated low-privilege user to determine whether restricted documents exist in a specified locale and mode, including draft mode. The endpoint returns localized document identifiers without applying document-level view or edit authorization criteria. This issue is fixed in version 4.33.0.
