CVE-2026-46442— Flowise 代码注入漏洞

Flowise: Authenticated Host RCE via POST /api/v1/node-custom-function and NodeVM Sandbox Escape

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, POST /api/v1/node-custom-function lacks route-level authorization, allowing any authenticated user or API key to submit arbitrary JavaScript to the Custom JS Function node. When E2B_APIKEY is not configured — the common deployment case — Flowise executes this code inside a NodeVM sandbox. This sandbox can be escaped, allowing an attacker to reach the host process object and execute system commands via child_process. The result is authenticated remote code execution on the Flowise server host. This issue has been patched in version 3.1.2.

Flowise 代码注入漏洞

Flowise是FlowiseAI开源的一个用于轻松构建 LLM 应用程序的工具。 Flowise 3.1.2之前版本存在代码注入漏洞，该漏洞源于POST /api/v1/node-custom-function端点缺乏路由级授权，可能导致远程代码执行。
