{"id":"CVE-2026-49463","summary":"NL Portal: Missing per-user authorization on document and decision GraphQL queries in nl-portal-backend-libraries","details":"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.","aliases":["GHSA-qpm9-h556-mwxm"],"modified":"2026-09-13T03:30:40.101808102Z","published":"2026-09-11T19:29:56.465Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-200","CWE-285"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49463.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49463.json"},{"type":"ADVISORY","url":"https://github.com/nl-portal/nl-portal-backend-libraries/security/advisories/GHSA-qpm9-h556-mwxm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49463"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nl-portal/nl-portal-backend-libraries","events":[{"introduced":"0"},{"fixed":"b8a353c4bcf87b44a6ce70e4bd605518fccb518e"}],"database_specific":{"extracted_events":[{"introduced":"1.5.0"},{"fixed":"3.0.1"},{"introduced":"0"}],"source":"AFFECTED_FIELD"}}],"versions":["1.0.8.RELEASE","1.2.5.RELEASE","1.1.1.RELEASE","SNAPSHOT","1.0.7.RELEASE","1.0.6.RELEASE","1.0.5.RELEASE","1.0.3.RELEASE","1.0.2.RELEASE","1.0.1.RELEASE","1.0.0.RELEASE","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49463.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
