Doc Text:
A flaw was found in Apache Airflow. The command-line interface (CLI) records command arguments in audit logs but masks sensitive values based on positional argument placement rather than content. As a result, certain command structures leave sensitive data, such as passwords and connection parameters, stored in plain text. An authenticated user with read access to audit logs can retrieve these exposed credentials through the event-log application programming interface (API), bypassing access controls on sensitive resources.

Description OSIDB Bzimport 2026-11-09 10:01:54 UTC
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.
