🚨 Severity: CRITICAL
💡 Vulnerability: Used execSync with string interpolation on tempFile path in packages/core/src/reconcile.ts, posing a command injection risk.
🎯 Impact: Exploitation could allow arbitrary command execution on the host machine.
🔧 Fix: Replaced execSync with spawnSync, passed parameters safely via an array, and utilized process.execPath instead of a raw node string.
✅ Verification: Ran npm run lint and npm test successfully. Tests for reconcile and execution logic still pass. No regressions detected.
