{"cve":"CVE-2026-54683","nvd":{"published":"2026-10-15T18:17:27.003","modified":"2026-10-16T20:04:29.760","status":"Deferred","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.","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-285","CWE-639"],"references":["https://github.com/nl-portal/nl-portal-backend-libraries/commit/6e738a876ff9f581991b5b070706100b5516e183","https://github.com/nl-portal/nl-portal-backend-libraries/commit/e326e6db862f71f76dd46d3b17cbb5fa6f2fba02","https://github.com/nl-portal/nl-portal-backend-libraries/pull/684","https://github.com/nl-portal/nl-portal-backend-libraries/pull/690","https://github.com/nl-portal/nl-portal-backend-libraries/releases/tag/3.0.3.RELEASE"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-54683","score":0.00333,"percentile":0.26273,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jr45-52cw-69h5","url":"https://osv.dev/vulnerability/GHSA-jr45-52cw-69h5","summary":"NL Portal Backend Libraries: Document contents remained downloadable by any logged-in user (incomplete fix of CVE-2026-49463)","modified":"2026-06-18T17:41:30.180662Z","packages":[{"ecosystem":"Maven","name":"nl.nl-portal:documenten-api","purl":"pkg:maven/nl.nl-portal/documenten-api","ranges":["<3.0.3"],"fixed":["3.0.3"]}]}],"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).
