Details

As written in the advisory (Markdown source, shown as plain text).

The `origin` parameter passed to some of the endpoints like `/trigger` was vulnerable to XSS exploit. This issue affects Apache Airflow versions prior to 1.10.15. This is same as CVE-2020-13944 but the implemented fix in Airflow 1.10.13 did not fix the issue completely.
