Vulnerability Title
SSRF via HTTP Redirect Following in Langflow API Request Component
Source: CVE Program / CVE List V5
Vulnerability Description
IBM Langflow OSS 1.0.0 through 1.9.3 contains a Server-Side Request Forgery (SSRF) protection bypass vulnerability in the API Request component. An authenticated attacker with low-level privileges (flow author role) can bypass SSRF protections by enabling the follow_redirects parameter and supplying a public URL that redirects to internal/localhost addresses. The vulnerability exists because the application validates only the initial URL but does not re-validate redirect destinations. This allows attackers to access internal HTTP services, localhost endpoints, cloud metadata services, and private network resources that should be unreachable when SSRF protection is enabled. Successful exploitation can lead to disclosure of sensitive information including credentials, tokens, internal API responses, and administrative panel data.

Vulnerability Description
IBM Langflow OSS是美国IBM公司的一个开源的低代码可视化AI工作流构建工具，它让开发者能通过拖拽组件的方式快速搭建、部署和迭代AI智能体与RAG应用，同时支持用Python进行深度定制以集成企业系统。 IBM Langflow OSS 1.0.0版本至1.9.3版本存在服务端请求伪造漏洞，该漏洞源于API Request组件问题，应用仅验证初始URL而未重新验证重定向目标，可能导致经过身份验证的攻击者启用follow_redirects参数并提供重定向到内部/localhost地址的公网U
