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.","state":0,"publishedAt":"2026-09-24T21:54:58.005+00:00","modifiedAt":"2026-09-25T16:38:16.529+00:00","affected":[{"ecosystem":"https://pypi.python.org","name":"apache-airflow-providers-hashicorp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Airflow HashiCorp provider\",\n                    \"packageURL\": \"pkg:pypi/apache-airflow-providers-hashicorp\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.6.0\",\n                            \"lessThan\": \"4.8.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://pypi.python.org\",\n                    \"packageName\": \"apache-airflow-providers-hashicorp\"\n                }"}],"metrics":[],"references":["https://github.com/apache/airflow/pull/70006","https://lists.apache.org/thread/l0fogo9dh5v07vnsxnhoh3c74othkr51","https://www.cve.org/CVERecord?id=CVE-2026-68870","https://www.cve.org/CVERecord?id=CVE-2026-68871","https://www.cve.org/CVERecord?id=CVE-2026-68872","https://www.cve.org/CVERecord?id=CVE-2026-86465"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97636","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97636","identifiers":["CVE-2026-97636"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
