CISA Malcolm是美国CISA政府部门开源的一款面向威胁情报与安全审计的网络流量分析工具。 CISA Malcolm v26.06.0之前版本存在服务端请求伪造漏洞，该漏洞源于API端点接收用户提供的值并将其直接插入后端搜索和分析数据存储请求路径中，未限制其内容，可能导致经过身份验证的攻击者替换任意后端路径，利用应用程序自身提升的服务凭据访问非预期内部端点，从而枚举或读取后端数据存储中原本受限的内部配置和管理数据。

Vulnerability Title
Server-Side Request Forgery in Malcolm
Source: CVE Program / CVE List V5
Vulnerability Description
An application programming interface endpoint accepts a user-supplied value and interpolates it directly into the path of a backend request to the underlying search and analytics data store, without restricting its contents. This allows an authenticated attacker to substitute an arbitrary backend path, causing the application's own elevated service credentials to be used against unintended internal endpoints. This could allow an attacker to enumerate or read internal configuration and administrative data from the backend data store that would otherwise be restricted.
