How to fix?

Upgrade @acrontum/filesystem-template to version 0.0.2 or higher.

Overview

@acrontum/filesystem-template is a Filesystem templating engine and project scaffolding tool

Affected versions of this package are vulnerable to Arbitrary Command Injection due to the fetchRepo API missing sanitization of the href field of external input.

PoC:

const filesys = require("@acrontum/filesystem-template")
filesys.fetchRepo({"pathname":"/api/1", "href": "|touch /tmp/rce", "search":"456" })
