The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Insecure handling of archive contents during cleanup operations allowed arbitrary file deletion (CVE-2021-34363). Attackers controlling archive paths could traverse outside the target directory if path canonicalization checks are bypassed or missing during cleanup.
Command Injection: Failing to shell-escape directory names extracted from ZIP archives allowed arbitrary commands to execute when 'thefuck' recommended and ran corrective commands involving the unzipped folder name.
Command Injection: Failing to shell-escape directory names extracted from TAR archives allowed arbitrary command execution when generating corrective shell commands involving the extracted folder.
