CVSS 7.300000190734863 HIGH
A flaw was found in the `tarfile.extractall()` function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside the intended destination directory. This could lead to out-of-destination file reads or writes, potentially resulting in information disclosure or arbitrary file modification.
