A command injection vulnerability exists in 0xKoda WireMCP versions through 7f45f8b2b4adeb76be8c6227eefb38533fdd6b1e. The issue arises in the 'server.tool' function of 'index.js', within the Tshark CLI Command Handler component. This vulnerability allows for arbitrary OS command execution by injecting shell metacharacters into commands that are executed via 'child_process.exec'. The exploitation must be performed locally.
It is recommended to replace 'child_process.exec' with 'execFile' or 'spawn', using argument arrays and disabling shell execution. Additionally, apply strict input validation to all parameters exposed to MCP clients.
