Doc Text:
A flaw was found in Apache Airflow. The audit logging mechanism stores sensitive connection and variable secrets in cleartext because the secret-masking filter only checks for specific configured key names. An authenticated user with low privileges and read access to the audit logs can exploit this flaw to view sensitive credentials that they are not otherwise authorized to access.

Description OSIDB Bzimport 2026-11-09 10:01:32 UTC 
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.
