CVE-2026-68870: Apache Airflow Microsoft Azure provider: microsoft.azure Key Vault backend: team-scope guard bypass resolves another team's Connection or Variable

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-10 · updated 2026-10-24
• Weakness: CWE-639

Description

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.

Affected products

• Apache Software Foundation Apache Airflow Microsoft Azure provider: before 14.1.0 — fixed in 14.1.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Airflow Microsoft Azure provider 14.1.0. Check the vendor advisory for mitigations.
