Miggo AIRoot Cause Analysis

The vulnerability stemmed from insecure file permissions in temporary directories. Key evidence comes from: 1) The CWE-732 mapping (Incorrect Permission Assignment) 2) Patch commits moving files to ~/.scalac and adding OwnerOnlyChmod 3) Code comments about 'weak permissions' in /tmp/scala-devel 4) Security advisory explicitly mentioning the /tmp/scala-devel path. The identified functions are directly involved in creating and securing these temporary files, with the original implementations lacking proper permission hardening.
