## What is CVE-2026-68870?

CVE-2026-68870 is a medium-severity missing authorization vulnerability in Apache Airflow Microsoft Azure provider, published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key)
