Miggo AIRoot Cause Analysis

The vulnerability stemmed from multiple functions handling chart names without proper path sanitization. Key issues were:

  1. SaveDir/writeTarContents used chart names directly in path construction
  2. Metadata validation didn't check for path components
  3. Linting rules allowed invalid names All were patched by adding filepath.Base() checks and name validation, as seen in the commit diffs. The functions directly processing chart names without sanitization were the root cause.
