CVE-2026-86468— Apache Airflow: CLI argv masking misses Variable values and --conn-extra, persisting secrets in audit logs

Quick assessment

Affected
Apache Software Foundation Apache Airflow
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Airflow 的命令行界面（CLI）会将参数记录到审计日志中，并通过参数位置对敏感信息进行掩码处理。然而，部分支持的命令格式仍会导致敏感信息以明文形式留存，例如：在变量（Variable）命令末尾使用 参数、使用 参数，以及在 命令中使用内联的 参数。能够读取审计事件但被拒绝访问变量和连接（Connection）的用户，可通过事件日志 API 获取这些明文敏感值。 建议 Apache Airflow 用户升级至 3.4.0 或更高版本。请注意，升级前写入审计日志的条目仍保留明文敏感值：请清除受影响的

Vulnerability Title
Apache Airflow: CLI argv masking misses Variable values and --conn-extra, persisting secrets in audit logs
Source: CVE Program / CVE List V5
Vulnerability 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.
