CVE-2026-54183— Apache Airflow: Airflow Variables were not masked in the UI for authenticated users

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基金会开源的一个工作流调度和数据处理平台。 Apache Airflow 3.3.1之前版本存在信息泄露漏洞，该漏洞源于秘密掩码器的递归深度限制未处理列表、元组或集合中嵌套值，导致深层嵌套的变量值在UI中未掩码显示，可能造成敏感信息泄露。

Vulnerability Title
Apache Airflow: Airflow Variables were not masked in the UI for authenticated users
Source: CVE Program / CVE List V5
Vulnerability Description
Apache Airflow's secrets masker hides values stored under sensitive key names when they are displayed in the UI. The masker's recursion-depth limit did not descend into values nested inside a list, tuple, or set beyond that limit, so an Airflow Variable holding such a deeply-nested value was shown unmasked in the Variables UI. The exposure is limited to the UI: any authenticated user who can see the Variable in the UI can already read its full value through the Variables REST API, so this does not disclose data the user could not otherwise obtain — the masking is a shoulder-surfing defense for the UI, not an access-control boundary. This is an incomplete-fix follow-up to CVE-2026-42358, whose fix made only the dictionary walk unbounded; lists, tuples, and sets beyond the depth limit remained unmasked in the UI. Deployments that applied the CVE-2026-42358 fix should also upgrade to address this residual case. Upgrade to apache-airflow 3.3.1 or later.
