Technical description

ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, an authenticated editor with legitimate edit rights on a pre-existing ordinary page nested under a restricted parent can use the same-parent page move operation to change sibling ranks without create authorization on that parent. The non-default nesting must already exist, and the bypass is limited to sibling ordering rather than arbitrary content modification, confidentiality loss, or creation of the restricted nesting. This issue is fixed in version 4.33.0.

———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 4.33.0.4h CVE-2026-1136653.7 LOW

———ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, the notification module exposes PATCH and DELETE REST endpoints that perform operations directly on the underlying MongoDB collection without verifying that the requester is authenticated or owns the target notification. As a result, an unauthenticated attacker who obtains a valid notification ID can modify or permanently delete another user's notification. This issue is fixed in version 4.33.0.4h CVE-2026-1136604.3 MED

———ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, ApostropheCMS’s exist-in-locale API allows an authenticated low-privilege user to determine whether restricted documents exist in a specified locale and mode, including draft mode. The endpoint returns localized document identifiers without applying document-level view or edit authorization criteria. This issue is fixed in version 4.33.0.4h
