CVE-2026-112954 Details
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.
A vulnerability in ApostropheCMS prior to version 4.34.0 allows unauthenticated users to bypass public API projections in the REST API. This is achieved through the search and sort query builders, which can be used to infer hidden field values that are excluded from the API response. The vulnerability arises because the publicApiProjection does not properly govern these query builders, leading to a targeted disclosure of information that the projection was intended to conceal.
Update to ApostropheCMS version 4.34.0 or later, where this vulnerability has been patched.
