Miggo AIRoot Cause Analysis

The vulnerability description explicitly mentions the Execute class in shellutils using tempfile.mktemp. The Debian bug report and CVE analysis confirm this code pattern creates a race condition vulnerability. The function generates temporary filenames without atomic creation (via mktemp), leaving a window for attackers to hijack the file paths. The patched version (0.61.0) would have replaced mktemp with a secure method like tempfile.mkstemp.
