CVE-2026-19693

extract-zip arbitrary file write outside the destination directory via a symlink at the final path component PUBLISHED

Description (CNA)

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.
