CVE-2026-113668

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, the REST route GET /api/v1//:_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.
