Overview

next is a react framework.

Affected versions of this package are vulnerable to HTTP Request Smuggling due to the inconsistent interpretation of crafted HTTP requests. An attacker can desynchronize server responses and poison the response queue by sending specially crafted HTTP requests that exploit the rewrites feature.

Note: This patch includes Next.js 14.x.
