node-code-sandbox-mcp is a Node.js–based Model Context Protocol server that spins up disposable Docker containers to execute arbitrary JavaScript. Prior to 1.3.0, a command injection vulnerability exists in the node-code-sandbox-mcp MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to child_process.execSync, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges on the host machine, bypassing the sandbox protection of running code inside docker. This vulnerability is fixed in 1.3.0.

 https://cve.radiocsirt.org/vuln/ghsa-5w57-2ccq-8w95 GHSA-5w57-2ccq-8w95 — Node.js Sandbox MCP Server vulnerability can lead to Sandbox Escape via Command Injection 2026-10-15T21:41:03.763585+00:00

Affected: npm: node-code-sandbox-mcp

### Summary

A command injection vulnerability exists in the `node-code-sandbox-mcp` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.execSync`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges on the host machine, bypassing the sandbox protection of running code inside docker.

The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.).

### Details

The MCP Server exposes tools to run code inside a docker container. An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to generate code that read a file. Below some example of vulnerable code and different ways to test this vulnerability including a real example of indirect prompt injection that can lead to arbitrary command injection (bypassing sandboxing).

### Vulnerable code

The following snippet illustrates the vulnerable code pattern used in the MCP Server’s tooling. **Note**: These is only one instance, but similar patterns may exist elsewhere in the codebase. ```js // https://github.com/alfonsograziano/node-code-sandbox-mcp/blob/v1.2.0/src/tools/stop.ts#L22 import { execSync } from 'node:child_process'; ...
