Hi Airflow community, Please find below the information about a vulnerability which has been addressed in Apache Airflow v2.0.1:
*CVE-2021-26559: CWE-284 Improper Access Control on Configurations Endpoint for the Stable API* *Description*: Improper Access Control on Configurations Endpoint for the Stable API of Apache Airflow allows users with Viewer or User role to get Airflow Configurations including sensitive information even when `[webserver] expose_config` is set to `False` in `airflow.cfg`. This allowed a privilege escalation attack. This issue affects *Apache Airflow 2.0.0*. *Mitigation:*Upgrade to Airflow 2.0.1 or remove `can read on Configurations` permission from the roles like Viewer and Users if you want to restrict users with those roles to view configurations in 2.0.0. *Credits*: Apache Airflow would like to thank Ian Carroll for reporting this issue. Thanks. Kaxil @ Airflow PMC
