Severity: low

Affected versions:

- Apache Airflow (apache-airflow) 3.0.0 before < 3.0.5

Description:

An example dag `example_dag_decorator` had non-validated parameter
that allowed the UI user to redirect the example to a malicious server
and execute code on worker.

This however required that the example dags are enabled in production
(not default) or the example dag code copied to build your own similar
dag.

If you used the `example_dag_decorator` please review it and apply the
changes implemented in Airflow 3.0.5 accordingly.
