CVE-2025-8917: Python Tarfile Incomplete Symlink Validation
Tarfile extraction incorporates custom member validation (e.g., mitigating CVE-2007-4559) but fails to validate symbolic or hard link targets (`member.linkname`, `member.issym()`, `member.islnk()`). This omission allows path traversal via malicious tarfiles with links pointing outside the intended extraction directory. To fix, validate `linkname` destination
