CVE-2026-41014: Apache Airflow: per-DAG RBAC bypass on /ui/partitioned_dag_runs endpoints

• Severity: medium (CVSS 4.3 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: 2026-06-01 · updated 2026-07-21
• Weakness: CWE-862

Description

The partitioned_dag_runs endpoints in the Airflow UI enforced only asset-level access control, not per-Dag authorization. An authenticated UI/API user with global Asset:read permission could enumerate partition run state, schedule configuration, and asset wiring for Dags they were not authorized to read. Affects deployments that rely on per-Dag read scoping while granting users broader Asset access. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.

Affected products

• Apache Airflow: from 3.2.0 before 3.2.2 — fixed in 3.2.2

How to fix

Upgrade to a fixed version: Apache Airflow 3.2.2. Check the vendor advisory for mitigations.
