Synopsis

Next.js 14.x < 14.2.25 Authorization Bypass

Description

The version of Next.js installed on the remote host is 11.1.4 prior to 13.5.6, 14.x prior to 14.2.25 or 15.x prior to 15.2.3. It is, therefore, affected by Authorization Bypass if the authorization check occurs in middleware.

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 version 14.2.25 or 15.2.3 or later.
