Miggo AIRoot Cause Analysis

The vulnerability stems from the insecure temporary file path configuration in the argument parser setup within the main() function. The GitHub patch specifically modifies the default log-file path from '/tmp/{prog_name}.log' to '{prog_name}.log', explicitly addressing the symlink attack vector by avoiding the insecure /tmp directory. The main() function is directly responsible for setting this vulnerable default path, making it the clear source of the vulnerability.
