Severity: low

Affected versions:

- Apache Airflow 2.6.0 before 2.8.0

Description:

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
