Apache Airflow Yandex Lockbox backend allows cross-team secret disclosure
CVE-2026-68871 · GHSA-qmrf-jrpr-rjx6
- Affected
- PyPI apache-airflow-providers-yandex < 4.5.1
- Fixed in
- 4.5.1· Vendor fix available
- Issue
- The Yandex Lockbox secrets backend in Apache Airflow's Yandex provider resolved a team-scoped Connection or Variable id through the team-agnostic lookup when the team-scoped lookup missed. In a deployment running multi-team mode with this backend, a caller in one team could resolve a secret belonging to another team by supplying an id that spells out that team's namespace, obtaining its credentials in full. No unusual configuration is required beyond enabling multi-team mode and using this backend. Users are advised to upgrade to apache-airflow-providers-yandex 4.5.1 or later, which refuses the team-agnostic fall-through for an id that could name a team namespace.
Recommended action: Upgrade to 4.5.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
