Vulnerability from github – Published: 2026-04-18 09:30 – Updated: 2026-04-20 18:31

Details

An example of BashOperator in Airflow documentation suggested a way of passing dag_run.conf in the way that could cause unsanitized user input to be used to escalate privileges of UI user to allow execute code on worker. Users should review if any of their own DAGs have adopted this incorrect advice.

Severity ?

8.8 (High)
