CVE-2026-86465Network attack vectorHinoki check available

Cross-team secret disclosure via path-shaped key

Published Sep 16, 2026 · Updated Sep 16, 2026

Information disclosure in Apache Airflow Akeyless provider before 0.3.1 allows remote authenticated users to read another team's secrets. AkeylessBackend concatenates an unvalidated, path-shaped Variable key after a team-scoped lookup misses, allowing the fallback path to name another team's namespace. Exploitation requires a multi-team deployment using the Akeyless secrets backend and DAG-author access; single-team deployments lack the boundary being bypassed.
