🎯 What: Fix Zip Slip and directory traversal vulnerabilities in unzip_archive and untar_archive by implementing filesystem-level canonicalization checks for symlinks.
⚠️ Risk: Without these checks, malicious archives could overwrite arbitrary files outside the destination directory via symlink traversal, potentially leading to arbitrary code execution.
🛡️ Solution: Manually process archive entries by incrementally building paths and verifying canonicalized paths start with the canonicalized destination directory, preventing both path traversal and symlink escapes.
