SCA: security update for next (GHSA-h27x-g6w4-24gq)

medium Tenable Cloud Security Plugin ID 438898

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Next.js is a React framework for building full-stack web applications. Starting in version 16.0.1 and
 prior to version 16.1.7, a request containing the `next-resume: 1` header (corresponding with a PPR resume
 request) would buffer request bodies without consistently enforcing `maxPostponedStateSize` in certain
 setups. The previous mitigation protected minimal-mode deployments, but equivalent non-minimal deployments
 remained vulnerable to the same unbounded postponed resume-body buffering behavior. In applications using
 the App Router with Partial Prerendering capability enabled (via `experimental.ppr` or `cacheComponents`),
 an attacker could send oversized `next-resume` POST payloads that were buffered without consistent size
 enforcement in non-minimal deployments, causing excessive memory usage and potential denial of service.
 This is fixed in version 16.1.7 by enforcing size limits across all postponed-body buffering paths and
 erroring when limits are exceeded. If upgrading is not immediately possible, block requests containing the
 `next-resume` header, as this is never valid to be sent from an untrusted client. (CVE-2026-27979)

Solution

Update the next library and its related packages to version 16.1.7 or later.
