CVE-2026-111453: Apache Airflow queued events deletion privilege escalation

CVE-2026-111453 · Severity: info · Published 2026-11-09

Apache Airflow is a workflow orchestration platform used to manage data pipelines and scheduled tasks. An authenticated user with edit permission on one workflow and read-only access to others could delete pending asset-triggered runs from workflows they cannot edit, disrupting operations and suppressing legitimate workflow executions. This affects users who upgraded to version 3.3.2 to fix a related issue and must upgrade to 3.4.0 or later.

Technologies: Apache Airflow. Vendors: Apache.

How to fix

  • Fixed in: Apache Airflow 3.4.0 and later

Technical details

The API endpoint DELETE /assets/{asset_id}/queuedEvents checked Dag edit permission against an optional dag_id query parameter but actually deleted queued events for all Dags the user could read, creating a permission bypass. An authenticated user with edit permission on one Dag and read access to others could suppress asset-triggered runs of Dags they cannot edit by calling the endpoint without supplying a dag_id, allowing the deletion scope to bypass the intended permission check.

Affected products

  • Apache Airflow 3.3.2 and earlier, before 3.4.0

Timeline

  • 2026-11-09: disclosed
