CVE-2026-95660 · Severity: medium · CVSS 6.3 · Published 2026-09-22

Moonshot AI Kimi Code is a development environment that automatically loads Model Context Protocol (MCP) configurations from project files. An attacker can craft a malicious .mcp.json file in a project directory that executes arbitrary OS commands when a user opens the project, without any explicit user action or confirmation beyond opening the workspace. This allows code execution with the same privileges as the user running Kimi Code.

## Technical details

The vulnerability is an OS command injection in the MCP Configuration Loader component (agent-core-v2/src/agent/mcp/config-loader.ts) triggered by auto-execution of untrusted .mcp.json files from the project directory. The attack requires the victim to open a malicious project but does not require any user interaction beyond that. The fix resolves fd/stty binary names to absolute paths to prevent $PATH planting attacks that allow injecting executables before the actual commands are invoked.

## Affected products
