Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The apache-airflow-providers-edge3 package is vulnerable before version 2.0.0 when it was installed and configured on Airflow 2; the source notes this provider was development-only on Airflow 2. An attacker who can author DAGs can use an internal API that the provider enabled to run code in the webserver context, which DAG authors should not be able to do. The fix is to uninstall the provider on Airflow 2 and migrate to Airflow 3, since version 2.0.0 and later require Airflow 3 and remove the affected code; projects using Edge3 on Airflow 3 are not affected.
