AI-suggested
Upgrade Apache Airflow to version 3.4.0 or later. This version masks secret values in audit logs and restricts access to affected audit rows to authorized users only, effectively mitigating the vulnerability.
Description
Apache Airflow's audit log stored Connection and Variable secret values in cleartext in the `Log.extra` column because the secrets masker matched only on configured sensitive key names. An authenticated low-privilege user with read access to the event-log / audit API — with no prior access to the affected connection or variable — could read those rows and recover the credentials verbatim. Users should upgrade to apache-airflow 3.4.0 or later, which masks these values and restricts the affected audit rows to authorized users.
