Summary
Command Injection in git-tags-remote
Details

All versions of git-tags-remote 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.

The following proof-of-concept creates a file in /tmp: 

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));
Severity ?
7.2 (High)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
