Short explanation

A publicApiProjection bypass vulnerability exists in ApostropheCMS. This flaw allows unauthenticated users to target hidden field information through search and sort query builders.

Why does it matter?

It matters because it allows unauthorized attackers to make targeted inferences about hidden field values, posing an information disclosure risk.

Show the technical text from the sources

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.
