Miggo AIRoot Cause Analysis

The vulnerability stems from intermediate directory permissions in the filesystem cache. The commit diff shows the fix involved wrapping os.makedirs() with umask(0o077) in _createdir. This function's original implementation didn't account for Python 3.7+'s behavior where os.makedirs() doesn't apply mode to existing intermediate directories when exist_ok=True. The direct modification of this function in the security patch confirms its role in the vulnerability.
