ApostropheCMS: Unauthenticated publicApiProjection bypass via search and sort query builders in the public REST API
Impact
ApostropheCMS is an open-source Node.js content management system. Prior to 4.34.0, a public REST API type that uses publicApiProjection can expose excluded searchable or sortable field information through search membership and sort ordering oracles. Returned fields remain filtered by the projection, so the issue permits targeted inference about hidden values rather than an unrestricted field dump. This issue is fixed in version 4.34.0.
