Next.js 15.3.x < 15.3.6 Remote Code Execution

critical Web App Scanning Plugin ID 115775

Synopsis

Next.js 15.3.x < 15.3.6 Remote Code Execution

Description

The version of Next.js installed on the remote host is 15.0.x prior to 15.0.5, 15.1.x prior to 15.1.9, 15.2.x prior to 15.2.6, 15.3.x prior to 15.3.6, 15.4.x prior to 15.4.8, 15.5.x prior to 15.5.7 or 16.0.x prior to 16.0.7. It is, therefore, affected by an unauthenticated remote code execution vulnerability in React Server Components due to insecure deserialization of payloads sent to Server Function endpoints (React2Shell).

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 15.3.6 or later.
