{"schema":"threatline.record/2","record":{"id":"CVE-2026-97636","aliases":[],"summary":"Apache Airflow HashiCorp provider: HashiCorp Vault secrets backend: team-scope guard bypass via user-controlled key","details":"Apache Airflow HashiCorp provider: the HashiCorp Vault secrets backend's team-scope guard can be bypassed with a user-controlled key. In a multi-team deployment, a Dag author scoped to one team can supply a Variable key containing a path separator that causes the backend to resolve a secret belonging to a different team, because after the team-scoped lookup misses the backend falls back to a team-agnostic path concatenated from the unvalidated key. The Execution API Variables route accepts a path-shaped key, so this is reachable from ordinary Dag code.\n\nAffects multi-team deployments using the HashiCorp Vault secrets backend. Single-team deployments are not affected, as there is no cross-team boundary to cross. This is the same class as CVE-2026-86465, CVE-2026-68870, CVE-2026-68871 and CVE-2026-68872 in the Akeyless, Azure Key Vault, Yandex Lockbox and Amazon secrets backends.\n\nUsers of apache-airflow-providers-hashicorp are recommended to upgrade to version 4.8.0 or later, which fixes the issue.","categories":["Unclassified"],"product":"Apache Airflow HashiCorp provider","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97636","source_modified_at":"2026-09-25T16:38:16.529Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Airflow HashiCorp provider","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"4.6.0","lessThan":"4.8.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97636","source_modified_at":"2026-09-25T16:38:16.529Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache Airflow HashiCorp provider","ecosystem":null},"version":"4.8.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00374,"percentile":0.30188,"score_date":"2026-10-23"},"published_at":"2026-09-24T21:54:58.005Z","modified_at":"2026-09-25T16:38:16.529Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97636","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T16:38:16.529Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97636","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/apache/airflow/pull/70006","tags":["patch"]},{"source":"CVE List","url":"https://lists.apache.org/thread/l0fogo9dh5v07vnsxnhoh3c74othkr51","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-68870","tags":["related"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-68871","tags":["related"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-68872","tags":["related"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-86465","tags":["related"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-25T16:37:39.918441Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T16:38:16.529Z","content_hash":"ac86b7337d16b854bebbe5cd0034b8d2633dced0b8e696a44005dbd34193cf81"}}
