Overview
apostrophe is a content management system (CMS) for Node.js. It supports in-context editing, schema-driven content types, flexible widgets and a great deal more. This module contains everything necessary to build a website with ApostropheCMS.
Affected versions of this package are vulnerable to Missing Authorization due to missing document-level authorization checks in the POST /api/v1/@apostrophecms/i18n/exist-in-locale endpoint. An authenticated attacker with a low-privilege role, including guest, can submit known or guessed document IDs to determine whether restricted documents exist in specific locales and modes, including unpublished drafts, and obtain their localized identifiers. The endpoint accepts multiple IDs, enabling bulk enumeration.
Note: This issue does not directly expose document contents or grant write, publish, or delete permissions.
