godot-mcp has Command Injection via unsanitized projectPath

Disclosed: 04.02.2026
Updated: 11.10.2026 10:22

Impact

A Command Injection vulnerability in godot-mcp allows remote code execution. The executeOperation function passed user-controlled input (e.g., projectPath) directly to exec(), which spawns a shell. An attacker could inject shell metacharacters like $(command) or &calc to execute arbitrary commands with the privileges of the MCP server process.

This affects any tool that accepts projectPath, including create_scene, add_node, load_sprite, and others.

Patches

Fixed in version 0.1.1 by switching from exec() to execFile(), which does not invoke a shell.

Workarounds

None. Users should upgrade immediately.
