Detailsinfo

A vulnerability classified as critical has been found in alfonsograziano node-code-sandbox-mcp up to 1.2.x. Affected is the function child_process.execSync. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2025-53372 since 06/27/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1202.

Upgrading to version 1.3.0 eliminates this vulnerability.
