NL Portal Backend Libraries: Document contents remained downloadable by any logged-in user until 3.0.3 (incomplete fix of CVE-2026-49463)
Impact
NL Portal Backend Libraries versions before 3.0.3 allow any logged-in user to download document contents using the getDocumentContent GraphQL query or GET /api/documentapi/{documentapi}/document/{documentId}/content REST route, without checking ownership. A user with a valid login and another person's document identifier can read that document's contents, potentially including sensitive personal information. Document identifiers are random but can leak through other channels.

Original source description
NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. Prior to 3.0.3, both the getDocumentContent GraphQL query and GET /api/documentapi/{documentapi}/document/{documentId}/content REST route allow any authenticated portal user to retrieve a document without checking ownership of or another authorized relationship to it. A user with a valid login and another person's document identifier can read that document's contents, which may include sensitive personal information. Document identifiers are random and difficult to guess, but they can leak through other channels. This issue is fixed in version 3.0.3.
