Remote Memory Exposure in request

Quick fix

GHSA-7xfp-9c55-5vqj — request: upgrade to the fixed version with the command below.

npm install request@2.68.0

Details

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
