CVE-2026-33326 is a medium severity vulnerability in KeystoneJS versions prior to 6.5.2 that allows bypassing access control on the isFilterable field during findMany queries by exploiting the cursor parameter. This flaw enables attackers with limited privileges to confirm the existence of records based on protected field values, potentially leaking sensitive information. The vulnerability stems from incomplete patching after a previous related issue (CVE-2025-46720) where update and delete mutations were fixed but the cursor parameter in findMany queries was overlooked. Exploitation requires network access and low privileges but no user interaction. The issue has been fixed in KeystoneJS version 6.5.2. Organizations using vulnerable versions should upgrade promptly to prevent unauthorized data exposure.
