Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 OpenViking 0.3.4 之前的版本中存在一个服务器端请求伪造（SSRF）漏洞。该漏洞允许已认证的、低权限攻击者通过向资源 API 端点提交任意 URL，访问内部网络服务。攻击者可以向 /api/v1/resources 提交一个精心构造的 URL，使服务器启用重定向功能，向回环地址、RFC 1918 私网地址、本地链路地址或云元数据地址发起外部的 HEAD 和 GET 请求，然后通过正常的内容 API 读取响应，从而枚举并与内部服务进行交互。

Vulnerability Title
OpenViking < 0.3.4 SSRF via /api/v1/resources
Source: CVE Program / CVE List V5
Vulnerability Description
OpenViking before 0.3.4 contains a server-side request forgery vulnerability that allows authenticated low-privilege attackers to access internal network services by submitting arbitrary URLs to the resources API endpoint. Attackers can POST a crafted URL to /api/v1/resources, causing the server to issue outbound HEAD and GET requests with redirects enabled to loopback, RFC 1918, link-local, or cloud metadata addresses, then read back responses through normal content APIs to enumerate and interact with internal services.
