Overview
next is a react framework.
Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information via insufficient scoping of response cache keys in the server's route caching logic in base-server.ts. Because cache keys are not bound to their source route, a response cached for one route can be served for a different route that shares the same key, allowing an attacker to poison the cache and cause other users to receive incorrect or attacker-influenced responses, or to trigger a denial of service through cache corruption.
