How to fix EUVD-2026-23664?

Within 24 hours: Inventory all Apache Airflow deployments and identify those running versions 3.0.x through 3.1.x. Within 7 days: Apply vendor-released patch to upgrade Apache Airflow to version 3.2.0 or later across all affected environments. Within 30 days: Conduct access control audit to verify asset materialize permissions are correctly enforced and review DAG execution logs for unauthorized activity during the vulnerable period.

DescriptionNVD

UI / API User with asset materialize permission could trigger dags they had no access to. Users are advised to migrate to Airflow version 3.2.0 that fixes the issue.

AnalysisAI

Apache Airflow 3.0.x prior to 3.2.0 allows remote unauthenticated attackers to trigger unauthorized DAG (Directed Acyclic Graph) execution via the UI or API, bypassing asset materialize permission checks. Despite CVSS 7.5 HIGH, the CVSS vector (PR:N) contradicts the description's requirement for 'UI/API user with asset materialize permission', suggesting authentication IS required-a critical discrepancy that demands verification. …
