AnalysisAIv1 – Jul 26, 2026

Information disclosure in ApostropheCMS 4.28.0 and earlier allows unauthenticated attackers to bypass admin-configured field restrictions on the piece-type REST API, exposing sensitive content such as internal notes or draft metadata. Public exploit code is available, though the EPSS score (0.09%) indicates low current exploitation probability; no active exploitation has been confirmed.

DescriptionCVE.org

ApostropheCMS is an open-source Node.js content management system. Versions 4.28.0 and prior contain an authorization bypass vulnerability in the getRestQuery method of the @apostrophecms/piece-type module, where the method checks whether a MongoDB projection has already been set before applying the admin-configured publicApiProjection. An unauthenticated attacker can supply a project query parameter in the REST API request, which is processed by applyBuildersSafely before the permission check, pre-populating the projection state and causing the publicApiProjection to be skipped entirely. This allows disclosure of any field on publicly queryable documents that the administrator explicitly restricted from the public API, such as internal notes, draft content, or metadata. Exploitation is trivial, requiring only appending query parameters to a public URL with no authentication. This issue has been fixed in version 4.29.0.
