Miggo AIRoot Cause Analysis

The vulnerability manifests in command construction patterns across multiple files: 1) In instance.js, the stop method builds shell commands using user-controlled process names without proper sanitization. 2) In version.js, browser command paths are concatenated directly into execution commands. The pull request #124 specifically addresses these areas by implementing input sanitization (safe() function) and switching from exec to execFile. The PoC demonstrates exploitation through the Instance constructor and getPid method, which ties to the vulnerable command construction in instance.js.
