Description
Apache Airflow versions from 2.4.0 up to but not including 2.9.3 contain a code injection vulnerability (CWE-94) that allows authenticated DAG authors to execute arbitrary code in the scheduler context via a crafted doc_md parameter. This behavior violates the Airflow security model. The vulnerability is fixed in version 2.9.3 and later.
