• CVE-2026-113668: 0.32% estimated exploitation activity in the next 30 days; percentile 25.28 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The REST route GET /api/v1/<piece-type/:id/locales (and the equivalent page route) does not apply the publicApiCheckAsync gate that ApostropheCMS's other read routes enforce. An unauthenticated caller can therefore query this route for any document id and learn whether the document exists and which locales it is published in — a document-existence and locale-metadata disclosure that the read-API is otherwise supposed to gate. Affected - Repository: apostrophecms/apostrophe (monorepo package apostrophe). - Confirmed at 4.32.2 (commit d3ff8c9 == the shipped 4.32.2; unchanged at current HEAD). No fix at time of report. - Stack: Node.js / Express + MongoDB. - Endpoints: GET /api/v1/<piece-type/:id/locales and GET /api/v1/@apostrophecms/page/:id/locales. Technical detail - Unsafe: modules/@apostrophecms/piece-type/index.js:397 registers the :id/locales route with no publicApiCheckAsync. The page module has the same omission at modules/@apostrophecms/page/index.js:925. - Gated…

# Patch Next advisory brief: CVE-2026-113668

Advisory: ApostropheCMS: :_id/locales REST route omits the public-API authorization gate its sibling read routes enforce (unauthenticated doc-existence + locale metadata disclosure)
IDs: CVE-2026-113668, GHSA-gqh3-7856-rjjg
Record: https://patchnext.com/advisories/cve-2026-113668 (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.
