CVE-2023-49783Network attack vector

Unauthorized record modification via unchecked CSV import

Published Jan 23, 2024 · Updated Jun 17, 2025

Incorrect authorization in Silverstripe Admin allows remote authenticated users with create rights to alter records via CSV import. The ModelAdmin import path uses BulkLoader without enforcing its permission checks, so CSV rows update or delete records despite missing edit or delete rights. Affected releases are 1.0.0 through 1.13.18 and 2.0.0 through 2.1.7; exposure requires the import form to remain enabled.
