## Overview

### Summary

`Unzipper::unzip` extracts each archive entry to a path built from the entry's
**raw, attacker-controlled name** without any traversal check. A ZIP archive whose
entry names contain `../` components (or an absolute path) can therefore cause
files to be written **outside** the destination directory chosen by the caller —
a "zip-slip" / directory-traversal arbitrary file write (CWE-22 / CWE-23 /
CWE-36).

### Affected versions

All published versions are affected. `unzip` has only ever released `0.1.0`
(published 2017-12-23) and appears unmaintained, so **no fixed version is
available**.

### Proof of concept

A malicious archive with a single entry named `../ESCAPED.txt` extracted via
`Unzipper::unzip` writes `ESCAPED.txt` one level above the destination directory.

## Affected packages

- `unzip >= 0.0.0-0`

## Remediation

Refer to the advisory for the patched release.
