**Name of the Vulnerable Software and Affected Versions** Apache Airflow versions prior to 2.8.2 **Description** The issue is related to incorrect default permissions in Apache Airflow, allowing authenticated Ops and Viewers users to view all information on audit logs, including dag names and usernames they were not permitted to view. With version 2.8.2 and newer, Ops and Viewer users do not have audit log permission by default and need to be explicitly granted permissions to see the logs. Only admin users have audit log permission by default. **Recommendations** For Apache Airflow versions prior to 2.8.2, upgrade to version 2.8.2 or newer to mitigate the risk associated with this issue.

**Name of the Vulnerable Software and Affected Versions** Apache Airflow versions prior to 2.7.0 **Description** The issue is related to a session fixation vulnerability in the Airflow web interface, allowing an authenticated user to continue accessing the webserver even after their password has been reset by an admin. This vulnerability can be exploited by a remote attacker to hijack a user's session. When using the database session backend, existing sessions of the user are invalidated when the password is reset. However, when using the securecookie session backend, sessions are not invalidated and require changing the secure key and restarting the webserver. Users resetting their passwords are informed about this with a flash message warning in the UI. **Recommendations** Upgrade to Apache Airflow version 2.7.0 or newer to mitigate the risk associated with this issue. As a temporary workaround, consider manually cleaning the session database for the database session backend or changing the secure key and restarting the webserver for the securecookie session backend.
