AI-suggested

A patch is available in nl.nl-portal:besluiten version 3.0.1 that fixes the authorization issue. Users should upgrade to version 3.0.1 or later. As a temporary workaround, block the affected document-content and decision-related GraphQL operations or their GraphQL types entirely at the API gateway to prevent unauthorized access.

Description

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.
