    const fastify = require('fastify')()
    const options = {
        addToBody: true,

            stream.resume();
        }
    };
    fastify.register(require('fastify-multipart'), options);
    fastify.post('/', function (req, reply) {
        console.log(req.body.toString());
        reply.code(200).send();
    });
    fastify.listen(3000, () => {
        console.log(`server listening on ${fastify.server.address().port}`)
        const body =
            '--AaB03x\r\n' +
            'content-disposition: form-data; name="__proto__"; filename="file1.txt"\r\n' +

    Denial of Service (DoS)

    fastify is a web framework, for Node.js.

    Affected versions of the package are vulnerable to Denial of Service (DoS) attacks due to not limit the size of the payload before JSON parsing it. An attacker can send a request with Content-Type: application/json and a very large payload, causing the Node.js process to crash with an uncaughtException.

    How to fix Denial of Service (DoS)?

    Upgrade fastify to version 0.38.0 or higher.

    <0.38.0
