{"id":"CVE-2026-47660","summary":"Pathling: Explicit oauthMetadataUrl in bulk-submit allows OAuth client credential exfiltration","details":"Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, Pathling's bulk-submit operation allows an allowed submitter to supply an explicit `oauthMetadataUrl` parameter that is not validated against `pathling.bulkSubmit.allowableSources`. When present, the bulk-submit OAuth flow trusts metadata and the returned `token_endpoint` from the caller-chosen location, then builds outbound OAuth client authentication directly from the submitter's stored credentials. This is fixed in Pathling Server 2.0.0.","aliases":["GHSA-245h-c573-9vr5"],"modified":"2026-08-09T03:30:13.512133028Z","published":"2026-08-07T19:57:24.114Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-522","CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47660.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47660.json"},{"type":"ADVISORY","url":"https://github.com/aehrc/pathling/security/advisories/GHSA-245h-c573-9vr5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47660"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/aehrc/pathling","events":[{"introduced":"0"},{"fixed":"d31e6cab6c8fde1c9812ec6ec67d8d8def8414f3"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.0.0"}],"source":"AFFECTED_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47660.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
