{"id":"CVE-2026-49463","state":"PUBLISHED","title":"NL Portal: Missing per-user authorization on document and decision GraphQL queries in nl-portal-backend-libraries","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.","publishedAt":"2026-09-11T19:29:56.465Z","updatedAt":"2026-09-11T19:51:33.853Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["nl-portal nl.nl-portal:besluiten","nl-portal nl.nl-portal:documenten-api"],"affected":[{"vendor":"nl-portal","product":"nl.nl-portal:besluiten","versions":[{"version":">= 1.5.0, < 3.0.1","status":"affected"}]},{"vendor":"nl-portal","product":"nl.nl-portal:documenten-api","versions":[{"version":"< 3.0.1","status":"affected"}]}],"references":["https://github.com/nl-portal/nl-portal-backend-libraries/security/advisories/GHSA-qpm9-h556-mwxm"],"weaknesses":["CWE-200","CWE-285"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49463.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49463","state":"PUBLISHED","datePublished":"2026-09-11T19:29:56.465Z","dateUpdated":"2026-09-11T19:51:33.853Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-30T04:17:43.094Z"},"containers":{"cna":{"title":"NL Portal: Missing per-user authorization on document and decision GraphQL queries in nl-portal-backend-libraries","descriptions":[{"lang":"en","value":"NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations.
