Descriptions

In Apache Airflow prior to 2.3.4, an insecure umask was configured for numerous Airflow components when running with the `--daemon` flag which could result in a race condition giving world-writable files in the Airflow home directory and allowing local users to expose arbitrary file contents via the webserver.

En Apache Airflow versiones anteriores a 2.3.4, era configurado una máscara de usuario no segura para numerosos componentes de Airflow cuando es ejecutado con el flag "--daemon", lo que podía resultar en una condición de carrera que daba lugar a archivos de escritura mundial en el directorio principal de Airflow y permitía a usuarios locales exponer contenidos de archivos arbitrarios por medio del servidor web
