XSS in Apache Airflow
CVE-2023-47265
Apache Airflow, versions 2.6.0 through 2.7.3 has a stored XSS vulnerability that allows a DAG author to add an unbounded and not-sanitized javascript in the parameter description field of the DAG. This Javascript can be executed on the client side of any of the user who looks at the tasks in the browser sandbox. While this issue does not allow to exit the browser sandbox or manipulation of the server-side data - more than the DAG author already has, it allows to modify what the user looking at the DAG details sees in the browser - which opens up all kinds of possibilities of misleading other users. Users of Apache Airflow are recommended to upgrade to version 2.8.0 or newer to mitigate the risk associated with this vulnerability
