Next.js Framework 14.1.1 < 15.5.21 / 16.x < 16.2.11 SSRF

critical Nessus Plugin ID 330088

Synopsis

The Next.js Framework on the remote host is affected by a server-side request forgery vulnerability.

Description

The Next.js Framework on the remote host is affected by a server-side request forgery vulnerability:

 - When a Server Action forwards or redirects a request, an attacker can cause the server to send that outbound request to a malicious host (Server-Side Request Forgery). This requires the attacker's request to control Host-associated headers. In some configurations, it is also possible to obtain internal values that weaken middleware/proxy authorization. (CVE-2026-64649)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Next.js Framework version 15.5.21 or 16.2.11 or later.
