Miggo AIRoot Cause Analysis

The vulnerability stemmed from improper path sanitization in Git HTTP request handling. The commit diff shows the HTTP handler in http.go previously used raw user input (m[1]) to build repository paths. The patch introduced pathutil.Clean() and validation checks, confirming the vulnerability existed in the original path handling logic. The HTTP function's direct use of unsanitized user input for file system operations matches the CWE-22 path traversal pattern.
