Miggo AIRoot Cause Analysis

The core vulnerability exists in checkGraphvizInstalled which constructs a command using user-controlled graphVizPath and executes it via child_process.exec (vulnerable to shell injection). The .image(), .svg() and .dot() functions all trigger this vulnerable path. The commit diff shows the fix replaced exec with execFile and modified command construction, confirming the original insecure pattern. The PoC demonstrates exploitation through these entry points.
