Apache Druid是美国阿帕奇（Apache）基金会的一款使用Java语言编写的、面向列的开源分布式数据库。 Apache Druid 存在安全漏洞，该漏洞源于在 Druid ingestion system 中，InputSource 用于从某个数据源读取数据。但是，HTTP InputSource 允许经过身份验证的用户以 Druid 服务器进程的权限从其他来源读取数据，例如本地文件系统。 这不是用户直接访问 Druid 时的权限提升，因为 Druid 还提供了 Local InputSourc

Vulnerability Title
Apache Druid: The HTTP inputSource allows authenticated users to read data from other sources than intended (incomplete fix of CVE-2021-26920)
来源: CVE Program / CVE List V5
Vulnerability Description
In the Druid ingestion system, the InputSource is used for reading data from a certain data source. However, the HTTP InputSource allows authenticated users to read data from other sources than intended, such as the local file system, with the privileges of the Druid server process. This is not an elevation of privilege when users access Druid directly, since Druid also provides the Local InputSource, which allows the same level of access. But it is problematic when users interact with Druid indirectly through an application that allows users to specify the HTTP InputSource, but not the Local InputSource. In this case, users could bypass the application-level restriction by passing a file URL to the HTTP InputSource. This issue was previously mentioned as being fixed in 0.21.0 as per CVE-2021-26920 but was not fixed in 0.21.0 or 0.21.1.
