AI-suggested

Upgrade Apache Airflow to version 3.4.0 or later, where this issue is fixed. Additionally, purge audit log entries created before the upgrade that contain cleartext secrets and rotate any secrets that may have been exposed in those logs to prevent misuse.

Description

Apache Airflow versions prior to 3.4.0 have a vulnerability where sensitive information such as secrets can be logged in cleartext in audit logs due to incomplete masking of CLI arguments. This affects certain command arguments like trailing --description on Variable commands, --conn-extra, and inline --password in keycloak-auth-manager commands. Users with read access to audit logs but without Variable or Connection access can retrieve these secrets via the event-log API. The issue is fixed in version 3.4.0.
