Asymmetric denial of service In next

Description

A flaw was found in Next.js. Applications utilizing Partial Prerendering via the Cache Components feature are susceptible to connection exhaustion. A remote attacker can send crafted POST requests to a server action, triggering a request-body handling deadlock. This leaves connections open, consuming server resources and ultimately leading to a Denial of Service (DoS) for legitimate users.

Mitigation
