Summary

ApostropheCMS: :_id/locales REST route omits the public-API authorization gate its sibling read routes enforce (unauthenticated doc-existence + locale metadata disclosure)

Details

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 siblings: the read routes in the same module (e.g. getAll at piece-type/index.js:256-263) call publicApiCheckAsync (:263) to enforce the public-API access policy.
So the locales handler (which calls getLocales() for the document) runs for any caller regardless of the public-API gate the other read routes apply, returning the document's locale/publication metadata without authorization.

Impact

An unauthenticated caller can confirm the existence of a document by _id and enumerate its locales/publication state — information the read-API is meant to gate. Defensibly 4.3 (AC:H) given the opaque _id precondition (the caller needs a document id).

How it was verified (local only)

Reproduced against apostrophe@4.32.2 (== commit d3ff8c9) locally with synthetic content: - Source review confirmed the :_id/locales route lacks publicApiCheckAsync while the sibling read routes have it. - An unauthenticated GET /api/v1/<piece-type>/<_id>/locales returned the document's locale metadata (existence + locales), while the gated read routes (e.g. getAll) correctly required the public-API policy. - Control: the same route with the publicApiCheckAsync gate added (matching the siblings) denies the unauthenticated request — isolating the missing gate as the cause. Synthetic content only; nothing hosted was touched.

Remediation

Add the publicApiCheckAsync (or equivalent) authorization gate to the :_id/locales route in both the piece-type and page modules, matching the sibling read routes, so the locale/existence metadata is only returned to callers permitted by the public-API policy.

CVE-2026-113668 (GCVE-0-2026-113668)

Vulnerability from cvelistv5 – Published: 2026-10-20 17:32 – Updated: 2026-10-20 19:04

Title

ApostropheCMS: :_id/locales REST route omits the public-API authorization gate its sibling read routes enforce (unauthenticated doc-existence + locale metadata disclosure)

Summary

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, 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. This issue is fixed in version 4.33.0.
