Detailsinfo

A vulnerability was found in Coding-Solo godot-mcp up to 0.1.0. It has been declared as critical. Affected by this vulnerability is the function exec of the component Model Context Protocol. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Godot MCP is a Model Context Protocol (MCP) server for interacting with the Godot game engine. Prior to version 0.1.1, 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. This issue has been patched in version 0.1.1.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-25546 since 02/02/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 0.1.1 eliminates this vulnerability. Applying the patch 21c785d923cfdb471ea60323c13807d62dfecc5a is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
