CVE-2025-48881Network attack vector

Authenticated object access via missing permission checks

Published May 30, 2025 · Updated Jun 4, 2025

Incorrect authorization in Valtimo backend libraries allows remote authenticated users to read and alter Objecten API objects. The object-management and objecten-api modules sent list, view, create, modify, and delete operations without enforcing object-action permissions. Any logged-in user needs no relevant application role, but at least one object type must be configured; exposed object URLs also permit reading outside object-management views.
