SCA: security update for next (GHSA-mq59-m269-xvcx)

medium Tenable Cloud Security Plugin ID 438899

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, `origin: null` was treated as a "missing" origin during Server Action CSRF
 validation. As a result, requests from opaque contexts (such as sandboxed iframes) could bypass origin
 verification instead of being validated as cross-origin requests. An attacker could induce a victim
 browser to submit Server Actions from a sandboxed context, potentially executing state-changing actions
 with victim credentials (CSRF). This is fixed in version 16.1.7 by treating `'null'` as an explicit origin
 value and enforcing host/origin checks unless `'null'` is explicitly allowlisted in
 `experimental.serverActions.allowedOrigins`. If upgrading is not immediately possible, add CSRF tokens for
 sensitive Server Actions, prefer `SameSite=Strict` on sensitive auth cookies, and/or do not allow `'null'`
 in `serverActions.allowedOrigins` unless intentionally required and additionally protected.
 (CVE-2026-27978)

Solution

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