Descriptions

Apache Airflow, version 2.7.0 through 2.7.3, has a vulnerability that allows an attacker to trigger a DAG in a GET request without CSRF validation. As a result, it was possible for a malicious website opened in the same browser - by the user who also had Airflow UI opened - to trigger the execution of DAGs without the user's consent.
Users are advised to upgrade to version 2.8.0 or later which is not affected

Apache Airflow, desde versión 2.7.0 a 2.7.3, tiene una vulnerabilidad que permite a un atacante activar un DAG en una solicitud GET sin validación CSRF. Como resultado, era posible que un sitio web malicioso abierto en el mismo navegador (por el usuario que también tenía abierta la interfaz de usuario de Airflow) desencadenara la ejecución de DAG sin el consentimiento del usuario. Se recomienda a los usuarios que actualicen a la versión 2.8.0 o posterior, que no se ve afectada.
