CVE-2026-68970— Apache Airflow: Values of a list-shaped Variable are not masked in task logs and the Rendered Templates UI

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是美国Apache基金会开源的一套具有创建、管理和监控工作流程功能的开源平台。 Apache Airflow 3.3.1之前版本存在加密问题漏洞，该漏洞源于Task SDK未对JSON值为列表的Variable内容进行掩盖，导致秘密以明文形式出现在任务日志和Rendered Templates UI中，可能被已认证用户获取。

Vulnerability Title
Apache Airflow: Values of a list-shaped Variable are not masked in task logs and the Rendered Templates UI
Source: CVE Program / CVE List V5
Vulnerability Description
Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI. Masking was applied only when the deserialized value was a string or a dict; a list at the top level matched neither and was returned unmasked. Any authenticated user able to read the logs or rendered templates of a task that references such a Variable could recover the values, with no special configuration required. This is the list-shaped counterpart of CVE-2026-59244, whose fix covered the dict case only, so deployments that upgraded in response to that advisory remain affected and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later.
