Root Cause Analysis

The vulnerability stemmed from NuGet creating world-writable cache directories on Unix systems due to improper permission handling. The commit shows replacement of DirectoryUtility.CreateSharedDirectory (which ignored umask) with Directory.CreateDirectory (which respects umask). The added Migration1.Run function cleans up existing vulnerable directories, demonstrating the prior insecure state. These changes directly address CWE-269 by enforcing proper privilege management through umask compliance and directory permission corrections.
