CVE-2026-48828— Apache Airflow: Bulk JSON Variables bypass should_hide_value_for_key - redact() called without the key
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 Software Foundation Apache Airflow是Apache Software Foundation基金会的开源工作流调度与数据管道编排平台。 Apache Airflow 3.3.0之前版本存在信息泄露漏洞，该漏洞源于Bulk Variables API在调用redactor时未传递变量键，导致基于键的检查无法对JSON可解码的变量值生效，从而使已认证且在UI/API层面具有批量Variable读取权限的用户能够从本应触发编辑的键名对应的JSON变量中检索明文值，可能

Vulnerability Title
Apache Airflow: Bulk JSON Variables bypass should_hide_value_for_key - redact() called without the key
Source: CVE Program / CVE List V5
Vulnerability Description
The Bulk Variables API in Apache Airflow called the redactor without passing the variable's key, so the key-based `should_hide_value_for_key` check (which triggers on secret-suffixed key names like `*_password` / `*_token` / `*_secret`) could not fire for JSON-decodable variable values. An authenticated UI/API user with bulk Variable read permission could retrieve plaintext values from JSON variables whose key would otherwise trigger redaction. Affects deployments that store sensitive values in JSON-typed Airflow Variables under secret-suffixed key names. Users are advised to upgrade to `apache-airflow` 3.3.0 or later (the fix landed on `main` after 3.2.2; no 3.2.x backport).
