Arbitrary File Write via Archive Extraction (Zip Slip)

decompress-tar is a tar plugin for decompress.

Affected versions of this package are vulnerable to Arbitrary File Write via Archive Extraction (Zip Slip). It is possible to bypass the security measures provided by decompress and conduct ZIP path traversal through symlinks.


const decompress = require('decompress');

decompress('slip.tar.gz', 'dist').then(files => {


It is exploited using a specially crafted zip archive, that holds path traversal filenames. When exploited, a filename in a malicious archive is concatenated to the target extraction directory, which results in the final path ending up outside of the target folder. For instance, a zip may hold a file with a "../../file.exe" location and thus break out of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.

The following is an example of a zip archive with one benign file and one malicious file. Extracting the malicous file will result in traversing out of the target folder, ending up in /root/.ssh/ overwriting the authorized_keys file:

+2018-04-15 22:04:29 ..... 19 19 good.txt

+2018-04-15 22:04:42 ..... 20 20 ../../../../../../root/.ssh/authorized_keys


There is no fixed version for decompress-tar.

Denial of Service

  • Vulnerable module: node-fetch
  • Introduced through: node-fetch@1.7.3

Detailed paths

  • Introduced through: @bauxite/launcher-api-forge@0.4.0 node-fetch@1.7.3
    Remediation: Upgrade to node-fetch@2.6.1.


node-fetch is an A light-weight module that brings window.fetch to node.js

Affected versions of this package are vulnerable to Denial of Service. Node Fetch did not honor the size option after following a redirect, which means that when a content size was over the limit, a FetchError would never get thrown and the process would end without failure.


Upgrade node-fetch to version 2.6.1, 3.0.0-beta.9 or higher.
