CVE-2023-44401Network attack vector

Unauthorized record disclosure via paginated permission filtering

Published Jan 23, 2024 · Updated Jun 17, 2025

Incorrect authorization in Silverstripe GraphQL 4.0.0 through 4.3.6 and 5.0.0 through 5.1.2 allows remote attackers to read restricted ORM records. CanViewPermission::listPermissionCheck filters a lazy DataList, causing its SQL limit to pull replacement records after denied IDs are removed without running canView on those replacements. A public GraphQL endpoint exposes the flaw without authentication; otherwise, CMS access and record-specific view restrictions govern what data is disclosed.
