@keystone-6/core: `isFilterable` bypass via `cursor` parameter in findMany_CVE-2026-33326

4.3 / 10

MEDIUM

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

Description

Keystone is a content management system for Node.js. Prior to version 6.5.2, {field}.isFilterable access control can be bypassed in findMany queries by passing a cursor. This can be used to confirm the existence of records by protected field values. The fix for CVE-2025-46720 (field-level isFilterable bypass for update and delete mutations) added checks to the where parameter in update and delete mutations however the cursor parameter in findMany was not patched and accepts the same UniqueWhere input type. This issue has been patched in version 6.5.2.
