Security Advisories 🚨

🚨 Authorization Bypass in Next.js Middleware

Impact

It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware.

Patches

• For Next.js 15.x, this issue is fixed in 15.2.3
• For Next.js 14.x, this issue is fixed in 14.2.25
• For Next.js versions 11.1.4 thru 13.5.6, consult the below workaround.

Workaround

If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the x-middleware-subrequest header from reaching your Next.js application.
