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 to their source route in base-server.ts and related export/build pipeline files. When multiple routes share a cache key, a response generated for one route can be served to requests for a different route, allowing an attacker to cause incorrect cached content to be returned to users, resulting in limited availability impact through cache poisoning or stale-data delivery.
