{"id":"CVE-2026-97636","published":"2026-09-24T22:17:02.660","lastModified":"2026-09-25T17:17:21.137","description":"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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/airflow/pull/70006","tags":[]},{"url":"https://lists.apache.org/thread/l0fogo9dh5v07vnsxnhoh3c74othkr51","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-68870","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-68871","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-68872","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-86465","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/70006","tags":[]}],"hasPoc":true,"ai":null}
