Langflow has an Arbitrary File Write (RCE) via v2 API

Langflow is a tool for building and deploying AI-powered agents and workflows. Versions 1.2.0 through 1.8.1 have a bypass of the patch for CVE-2025-68478 (External Control of File Name), leading to the root architectural issue within `LocalStorageService` remaining unresolved. Because the underlying storage layer lacks boundary containment checks, the system relies entirely on the HTTP-layer `ValidatedFileName` dependency. This defense-in-depth failure leaves the `POST /api/v2/files/` endpoint vulnerable to Arbitrary File Write. The multipart upload filename bypasses the path-parameter guard, allowing authenticated attackers to write files anywhere on the host system, leading to Remote Code Execution (RCE). Version 1.9.0 contains an updated fix.

Langflow 访问控制错误漏洞

Langflow是Langflow开源的一个用于构建多代理和 RAG 应用程序的可视化框架。 Langflow 1.2.0至1.8.1版本存在访问控制错误漏洞，该漏洞源于底层存储层缺少边界检查，可能导致经过身份验证的攻击者执行任意文件写入和远程代码执行。
