Upgrade next to version 13.5.7, 14.2.10 or higher.
Overview
next is a react framework.
Affected versions of this package are vulnerable to Acceptance of Extraneous Untrusted Data With Trusted Data by sending a crafted HTTP request, which allows the attacker to poison the cache of a non-dynamic server-side rendered route in the page router. This will coerce the request to cache a route that is meant to not be cached and send a Cache-Control: s-maxage=1, a stale-while-revalidate header, which some upstream CDNs may cache as well.
Note:
This is only vulnerable if:
The user is using pages router
The user is using non-dynamic server-side rendered routes.
Users are not affected if:
They are using the app router
The deployments are on Vercel
