Kiro Global MCP Configuration Write to Host Code Execution

  • Autonomous Agents
  • System Compromise & RCE
  • Model Evasion & Bypass

Intezer and Kodem demonstrated that hidden instructions in a web page fetched by Kiro could induce its file-write tool to change ~/.kiro/settings/mcp.json without a meaningful approval boundary. Kiro reloaded the configuration and started the added MCP server command in the developer's user context. The proof of concept sent a local callback; it did not document an in-the-wild victim or theft of secrets.
