Description

A flaw was found in Next.js, a React framework for building web applications. This vulnerability, related to cache poisoning, affects applications utilizing React Server Components (RSC) when shared caches fail to properly partition response variants. A remote attacker can exploit this by causing an RSC response to be served from its original URL, thereby poisoning shared cache entries. As a result, subsequent visitors may receive unexpected component payloads instead of the intended HTML content.
