CVE-2026-50204— Apache Airflow: Audit-log secrets masker redacts by key name only, persisting connection and Variable secrets in cleartext

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 的审计日志在 列中以明文存储了 Connection（连接）和 Variable（变量）中的敏感值，这是因为其敏感信息掩码机制仅针对已配置的敏感键名进行匹配。任何拥有事件日志/审计 API 读取权限的认证低权限用户，即使此前无法访问受影响的连接或变量，也能读取这些日志行并完整还原凭证。建议用户升级至 Apache Airflow 3.4.0 或更高版本，该版本会对这些值进行掩码处理，并将受影响的审计日志行限制为仅授权用户可访问。

Vulnerability Title
Apache Airflow: Audit-log secrets masker redacts by key name only, persisting connection and Variable secrets in cleartext
Source: CVE Program / CVE List V5
Vulnerability Description
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.
