DescriptionCVE.org
NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. The `nl.nl-portal:documenten-api` package through version 3.0.0 and the `nl.nl-portal:besluiten` package from version 1.5.0 through 3.0.0 lack per-user authorization in GraphQL resolvers, allowing an authenticated user to access other users’ document contents, decisions, audit trails, and decision attachments. Version 3.0.1 contains a patch. As a workaround, block the affected document-content and decision-related GraphQL operations at the API gateway or block their GraphQL types entirely.
