wheel is a command line tool for manipulating Python wheel files,
as defined in PEP 427. In versions 0.46.1 and below, the unpack
function is vulnerable to file permission modification through
mishandling of file permissions after extraction. The logic blindly
trusts the filename from the archive header for the chmod operation,
even though the extraction process itself might have sanitized the
path. Attackers can craft a malicious wheel file that, when unpacked,
changes the permissions of critical system files (e.g., /etc/passwd,
SSH keys, config files), allowing for Privilege Escalation or
arbitrary code execution by modifying now-writable scripts. This
issue has been fixed in version 0.46.2.
