CVE-2026-68870 PUBLISHED

Apache Airflow Microsoft Azure provider: microsoft.azure Key Vault backend: team-scope guard bypass resolves another team's Connection or Variable

Assigner: apache
Reserved: 31.07.2026 Published: 10.08.2026 Updated: 10.08.2026

The Azure Key Vault secrets backend in Apache Airflow's Microsoft Azure 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-microsoft-azure 14.1.0 or later, which refuses the team-agnostic fall-through for an id that could name a team namespace.
