Next.js 14.x < 14.2.26 Information Disclosure

medium Web App Scanning Plugin ID 115784

Synopsis

Next.js 14.x < 14.2.26 Information Disclosure

Description

The version of Next.js installed on the remote host is 11.1.4 prior to 12.3.6, 13.0.x prior to 13.5.10, 14.x prior to 14.2.26 or 15.x prior to 15.2.4. It is, therefore, affected by an information disclosure vulnerability where the x-middleware-subrequest-id header may be leaked to external hosts.

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 14.2.26 or later.
