CVE-2020-7668: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

May 18, 2021 (updated January 4, 2022)

In all versions of the package github.com/unknwon/cae/tz, the ExtractTo function doesn’t securely escape file paths in zip archives which include leading or non-leading “..”. This allows an attacker to add or replace files system-wide.
