# CVE-2026-112957: ApostropheCMS: GET /api/v1/@apostrophecms/page/:id bypasses viewRole restriction and exposes viewPermission-gated fields to lower-privileged users

- Also known as: GHSA-VH56-5M88-39RQ
- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.34.0
- Published: 2026-10-20 · Updated: 2026-10-21

## Affected

- apostrophecms apostrophe: fixed in 4.34.0
- apostrophe (npm): fixed in 4.34.0

## 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.
