ApostropheCMS: Page REST API authorization bypass

CVE-2026-113670GHSA-2j32-q6rx-h844

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (apostrophe 4.33.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-113670

Advisory: ApostropheCMS: Page REST API authorization bypass
IDs: CVE-2026-113670, GHSA-2j32-q6rx-h844
Record: https://patchnext.com/advisories/cve-2026-113670 (revision 3, source checked 26 Oct 2026, 13:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: apostrophe 4.33.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm apostrophe: affected < 4.33.0; fixed in 4.33.0

## Suggested inspection (read-only)
- `npm ls apostrophe --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on apostrophe.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-2j32-q6rx-h844 (GitHub-reviewed advisory GHSA-2j32-q6rx-h844 lists affected ranges: npm apostrophe >=0 <4.33.0)
- Verified: https://osv.dev/vulnerability/GHSA-2j32-q6rx-h844 (OSV record GHSA-2j32-q6rx-h844 lists affected ranges: npm apostrophe >=0 <4.33.0 (fixed))
