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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200","CWE-285"],"references":["https://github.com/nl-portal/nl-portal-backend-libraries/security/advisories/GHSA-qpm9-h556-mwxm"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-49463","score":0.0034,"percentile":0.27262,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qpm9-h556-mwxm","url":"https://osv.dev/vulnerability/GHSA-qpm9-h556-mwxm","summary":"NL Portal: Missing per-user authorization on document and decision GraphQL queries in nl-portal-backend-libraries","modified":"2026-07-08T21:26:36.977246Z","packages":[{"ecosystem":"Maven","name":"nl.nl-portal:documenten-api","purl":"pkg:maven/nl.nl-portal/documenten-api","ranges":["<3.0.1"],"fixed":["3.0.1"]},{"ecosystem":"Maven","name":"nl.nl-portal:besluiten","purl":"pkg:maven/nl.nl-portal/besluiten","ranges":[">=1.5.0 <3.0.1"],"fixed":["3.0.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
