This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
