An issue was found in Apache Airflow versions 1.10.10 and below. It was discovered that many of the admin management screens in the new/RBAC UI handled escaping incorrectly, allowing authenticated users with appropriate permissions to create stored XSS attacks.
A malicious admin user could edit the state of objects in the Airflow metadata database to execute arbitrary javascript on certain page views. This also presented a Local File Disclosure vulnerability to any file readable by the webserver process.
