CVE-2026-19693: Max-Mapper Extract-Zip

High severity, CVSS 8.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Max-Mapper Extract-Zip: from 1.0.0, up to and including 2.0.1
