ApostropheCMS: GET /api/v1/@apostrophecms/page/:id bypasses viewRole restriction and exposes viewPermission-gated fields to lower-privileged users

Published Oct 20, 2026 · Updated Oct 21, 2026 · Assigned by GitHub_M

Description

ApostropheCMS is an open-source Node.js content management system. Prior to 4.34.0, the getOne REST endpoint for pages does not apply viewRole type-level restrictions or viewPermission field-level redaction. An editor-level user who knows a document _id can read the full content of admin-only pages and their privileged fields, while the getAll endpoint correctly enforces both restrictions. This issue is fixed in version 4.34.0.
