CVE-2026-111455— Apache Airflow: Connections API: async connection test authorizes create at enqueue but overwrites a later-created connection at commit

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 的异步连接测试功能仅在测试任务入队时检查权限：若连接 ID 尚不存在，仅验证“创建”权限。然而，当测试以 模式完成时，会将测试后的连接以该 ID 写入。这导致仅拥有“创建”权限而无“编辑”权限的用户，能够覆盖由其他用户在此期间创建的同名连接。该漏洞仅影响启用了非默认配置项 的部署环境。建议用户升级至 Apache Airflow 3.4.0 或更高版本以修复此问题。

Vulnerability Title
Apache Airflow: Connections API: async connection test authorizes create at enqueue but overwrites a later-created connection at commit
Source: CVE Program / CVE List V5
Vulnerability Description
Apache Airflow's asynchronous connection test checked permissions when the test was queued — only create permission when the connection ID did not exist yet — but, when the test completed with `commit_on_success`, wrote the tested connection under that ID. A user allowed to create but not edit connections could overwrite a connection someone else had created in the meantime. Only deployments that enable the non-default `[core] test_connection` setting are affected. Users are advised to upgrade to apache-airflow 3.4.0 or later.
