Moonshot AI Kimi Code up to 0.31.0 MCP Configuration Loader config-loader.ts os command injection

Summaryinfo

A vulnerability was found in Moonshot AI Kimi Code up to 0.31.0. It has been rated as critical. The impacted element is an unknown function of the file agent-core-v2/src/agent/mcp/config-loader.ts of the component MCP Configuration Loader. This manipulation causes os command injection. This vulnerability is registered as CVE-2026-95660. Remote exploitation of the attack is possible. Furthermore, an exploit is available. Upgrading the affected component is advised. Beyond the trust prompt, the fix resolves fd/stty binaries to absolute paths specifically "so untrusted workspaces cannot plant bare-name executables before confirmation," fixing a secondary $PATH path-planting vector alongside the primary untrusted-.mcp.json auto-spawn.
