What is CVE-2024-26280?
CVE-2024-26280 is a medium-severity missing authorization vulnerability in Apache Airflow, published on 1 Mar 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
Apache Airflow, versions before 2.8.2, has a vulnerability that allows authenticated Ops and Viewers users to view all information on audit logs, including dag names and usernames they were not permitted to view. With 2.8.2 and newer, Ops and Viewer users do not have audit log permission by default, they need to be explicitly granted permissions to see the logs.
