extract-zip <=2.0.1 Arbitrary File Write via Symlink
CVE-2026-19693 Published on August 17, 2026
extract-zip arbitrary file write outside the destination directory via a symlink at the final path component
extract-zip through 2.0.1 containment-checks only the parent directory of each archive entry and never the entry's own final path component, so an archive containing two entries with identical names - a symlink whose target is outside the destination, followed by a regular file - writes through the planted symlink and yields an arbitrary file write outside the destination directory.
