CVE-2026-97636Hinoki check available

Cross-team secret disclosure via fallback path

Published Sep 24, 2026 · Updated Sep 24, 2026

Information disclosure in Apache Airflow HashiCorp Provider 4.6.0 through 4.7.2 allows remote authenticated users to read cross-team secrets. VaultBackend accepts a path-shaped Variable key and, after a team-scoped lookup misses, appends that unvalidated key to a team-agnostic base path. Exploitation requires a multi-team deployment using the HashiCorp Vault secrets backend; single-team deployments have no cross-team boundary.
