Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
