`unzip`: archive extraction is vulnerable to path traversal (zip-slip)
Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published### 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.
