Subject: CVE-2026-86468: Apache Airflow: CLI argv masking misses Variable
values and --conn-extra, persisting secrets in audit logs
Severity: low
Affected versions:
- Apache Airflow before 3.4.0
Description:
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.
