SCA: security update for next (GHSA-955p-x3mx-jcvp)

medium Tenable Self-Hosted Container Security Plugin ID 445135

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. In versions 12.0.0 through 15.5.20
 and 16.0.0 through 16.2.10, Next.js applications using App Router, Server Actions (use server) or use
 cache endpoints can be disclosed bypassing any authentication on the pages where these endpoints are
 usually used. Server Action IDs can be disclosed to unauthenticated users via publicly served client
 artifacts (for example, static chunks containing action references). Affected users are applications using
 App Router and Server Actions. By itself, this disclosure is typically a recon/enumeration primitive;
 however, it can increase risk when combined with other weaknesses. This issue has been fixed in versions
 15.5.21 and 16.2.11. (CVE-2026-64643)

Solution

Update the next library and its related packages to version 15.5.21 or later.
