CVE-2026-44574— Next.js 安全漏洞

Next.js: Middleware / Proxy bypass through dynamic route parameter injection

Next.js is a React framework for building full-stack web applications. From 15.4.0 to before 15.5.16 and 16.2.5, applications that rely on middleware to protect dynamic routes can be vulnerable to authorization bypass. In affected deployments, specially crafted query parameters can alter the dynamic route value seen by the page while leaving the visible path unchanged, which can allow protected content to be rendered without passing the expected middleware check. This vulnerability is fixed in 15.5.16 and 16.2.5.

使用候选路径或通道进行的认证绕过

Next.js 安全漏洞

Next.js是Vercel开源的一个 React 框架。 Next.js 15.4.0至15.5.16之前版本和16.2.5之前版本存在安全漏洞，该漏洞源于依赖中间件保护动态路由时，特制查询参数可改变页面看到的动态路由值而保持可见路径不变，可能导致绕过授权检查访问受保护内容。
