Miggo AIRoot Cause Analysis

  1. Multiple sources (GitHub Advisory, Snyk, NVD) explicitly name a.getProcessPortId as the injection vector
  2. The provided PoC demonstrates command injection through this function's parameter
  3. The package's purpose (killing processes by port) inherently requires executing system commands
  4. CWE-77 classification confirms improper neutralization in command execution
  5. Lack of path information is offset by clear function identification in vulnerability descriptions
