{"id":"CVE-2026-47663","summary":"Pathling: Typed CRUD/search/batch providers can lead to server-wide PHI exfiltration and cross-resource mutation","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 typed CRUD/search/batch FHIR surface allows an authenticated caller with only coarse operation authorities to act on attacker-chosen resource families because those entrypoints do not consistently enforce the documented per-resource `read` and `write` authorities. The documented authorization model requires an operation authority (e.g. `pathling:search`) to be paired with the matching per-resource `read` or `write` authority (e.g. `pathling:read:Patient`). Delete and batch are documented to require write authority for all referenced resource types. However, typed search, update, and related handlers are annotated only with `@OperationAccess(...)` and act on the provider-selected resource type without checking the corresponding per-resource authority. This is fixed in Pathling Server 2.0.0.","aliases":["GHSA-q62q-2m46-r7rv"],"modified":"2026-08-09T03:30:31.212579411Z","published":"2026-08-07T20:26:08.349Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-285"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47663.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47663.json"},{"type":"ADVISORY","url":"https://github.com/aehrc/pathling/security/advisories/GHSA-q62q-2m46-r7rv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47663"}],"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-2026-47663.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"}]}
