Default behavior of Fastifys versioned routes can be used for cache poisoning when Fastify is used in combination with a http cache / CDN

I would like to report possible cache poisoning in Fastify It allows an attacker to perform an cache poisoning when Fastify is used in combination with a http cache / CDN.

const app = require('fastify')();

app.get('/', async () => {
    return { hello: 'world' };
});

const start = async () => {
    await app.listen(9000)
}
start();
