CVE-2026-19693extract-zip arbitrary file write outside the destination directory via a symlink at the final path component
High 8.1
In plain English
A high-severity path traversal in extract-zip from max-mapper. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 39% of all known vulnerabilities).
Official description
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.
