Short explanation
Apache Airflow CLI argv masking misses certain command shapes while masking secrets by argument position, leaving sensitive data in cleartext within audit logs [S0].
Users who are denied Variable and Connection access can retrieve these cleartext secret values through the event-log API if they can read audit events [S0].
What should be done?
- Upgrade apache-airflow to version 3.4.0 or later [S0]
- Purge affected audit-log entries written before the upgrade [S0]
- Rotate the secrets contained within the affected log entries [S0]
Chain of evidence and sources
Apache Airflow CLI argüman maskelemesi belirli komut biçimlerinde gizli bilgileri açık metin olarak bırakmaktadır [S0].
Etkilenen kullanıcılar apache-airflow 3.4.0 veya sonraki bir sürümüne yükseltmelidir [S0].
Show the technical text from the sources
Apache Airflow's CLI records its arguments in the audit log but masks secrets by argument position, so some supported command shapes leave secrets in cleartext, for example a trailing `--description` on Variable commands, `--conn-extra`, and the inline `--password` of `airflow keycloak-auth-manager` commands. A user who can read audit events but is denied Variable and Connection access can retrieve those values through the event-log API. Users of apache-airflow are recommended to upgrade to 3.4.0 or later. Audit-log entries written before the upgrade keep the cleartext values: purge the affected entries and rotate the secrets they contain.
