NocoBase Affected by Sandbox Escape to RCE via console._stdout Prototype Chain Traversal in Workflow Script Node

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.28, NocoBase's Workflow Script Node executes user-supplied JavaScript inside a Node.js vm sandbox with a custom require allowlist (controlled by WORKFLOW_SCRIPT_MODULES env var). However, the console object passed into the sandbox context exposes host-realm WritableWorkerStdio stream objects via console._stdout and console._stderr. An authenticated attacker can traverse the prototype chain to escape the sandbox and achieve Remote Code Execution as root. This issue has been patched in version 2.0.28.

动态管理代码资源的控制不恰当

Nocobase 安全漏洞

Nocobase是NocoBase开源的一个低代码平台。 NocoBase 2.0.28之前版本存在安全漏洞，该漏洞源于工作流脚本节点在Node.js vm沙箱中执行用户提供的JavaScript时，传递给沙箱环境的console对象暴露了主机领域的WritableWorkerStdio流对象，可能导致经过身份验证的攻击者遍历原型链以逃逸沙箱并实现远程代码执行。
