Summary
ApostropheCMS, an open-source Node.js content management system, before 4.33.0 has a REST route for document locales that skips the public API authorization check used by its other read routes (CWE-862). An unauthenticated remote attacker can query any document _id to learn whether the document exists and which locales it is published in.

Description from the CNA
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.
