The session fixation vulnerability allowed the authenticated user to continue accessing Airflow webserver even after the password of the user has been reset by the admin - up until the expiry of the session of the user. Other than manually cleaning the session database (for database session backend), or changing the securekey and restarting the webserver, there were no mechanisms to force-logout the user (and all other users with that).

With this fix implemented, when using the database session backend, the existing sessions of the user are invalidated when the password of the user is reset. When using the securecookie session backend, the sessions are NOT invalidated and still require changing the secure key and restarting the webserver (and logging out all other users), but the user resetting the password is informed about it with a flash message warning displayed in the UI. Documentation is also updated explaining this behaviour.

Users of Apache Airflow are advised to upgrade to version 2.7.0 or newer to mitigate the risk associated with this vulnerability.

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

Airflow versions 2.7.0 through 2.8.4 have a vulnerability that allows an authenticated user to see sensitive provider configuration via the "configuration" UI page when "non-sensitive-only" was set as "webserver.exposeconfig" configuration (The celery provider is the only community provider currently that has sensitive configurations). You should migrate to Airflow 2.9 or change your "exposeconfig" configuration to False as a workaround. This is similar, but different to CVE-2023-46288 https://github.com/advisories/GHSA-9qqg-mh7c-chfq which concerned API, not UI configuration page.

Apache Airflow, versions 2.7.0 and 2.7.1, is affected by a vulnerability that allows an authenticated user to retrieve sensitive configuration information when the "exposeconfig" option is set to "non-sensitive-only". The exposeconfig option is False by default. It is recommended to upgrade to a version that is not affected.
