Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Path Traversal: Unsafe extraction of tar archives using standard library functions allows arbitrary file writes. This was mitigated by introducing explicit path validation checks during extraction.

Insecure Deserialization: The project depended on outdated versions of nemo-toolkit susceptible to remote code execution (CVE-2025-33245, CVE-2025-33253). Security relies on maintaining strict, upgraded dependency pin minimums.

Path Traversal: Separate download utilities implemented unsafe tar extraction. Resolving this required implementing custom validation for absolute paths, traversal sequences, and symbolic links before extraction.
