Summary

In privsim mcp-test-runner 0.2.0, the child_process.spawn function in src/index.ts (MCP interface) allows OS command injection through manipulation of the command argument. The attack can be launched remotely, and the exploit has been publicly disclosed.

Risk Assessment

An attacker may execute arbitrary system commands on the host running mcp-test-runner, potentially leading to system compromise. Public availability of the exploit increases the risk of exploitation.

Recommendation

Restrict access to the MCP interface and avoid passing untrusted data to the command argument. Consider suspending use of mcp-test-runner 0.2.0 until the project releases a fix.
