Nuxt allows DOS via cache poisoning with payload rendering response
Details
### Summary
By sending a crafted HTTP request to a server behind an CDN, it is possible in some circumstances to poison the CDN cache and highly impacts the availability of a site.
It is possible to craft a request, such as `https://mysite.com/?/_payload.json` which will be rendered as JSON. If the CDN in front of a Nuxt site ignores the query string when determining whether to cache a route, then this JSON response could be served to future visitors to the site.
### Impact
An attacker can perform this attack to a vulnerable site in order to make a site unavailable indefinitely. It is also possible in the case where the cache will be reset to make a small script to send a request each X seconds (=caching duration) so that the cache is permanently poisoned making the site completely unavailable.
## Conclusion :
This is similar to a vulnerability in Next.js that resulted in CVE-2024-46982 (and see [this article](https://zhero-web-sec.github.io/research-and-things/nextjs-cache-and-chains-the-stale-elixir), in particular the "Internal URL parameter and pageProps" part, the latter being very similar to the one concerning us here.)
