Next.js 13.0.0 < 15.5.15 Denial of Service

high Web App Scanning Plugin ID 115758

Synopsis

Next.js 13.0.0 < 15.5.15 Denial of Service

Description

The version of Next.js installed on the remote host is 13.0.0 prior to 15.5.15 or 16.0.0 prior to 16.2.3. It is, therefore, affected by a denial of service vulnerability with Server Components, allowing an unauthenticated remote attacker to send crafted requests to Server Function endpoints that exhaust server resources.

Note that the scanner has not attempted to exploit this issue but has instead relied only on application's self-reported version number.

Solution

Upgrade to Next.js version 15.5.15 or later.
