Echo: next: security update to 15.5.24

critical Tenable Cloud Security Plugin ID 461954

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. From 13.4.0 until 15.5.24 and
16.3.3, Next.js applications using Pages Router or App Router without Cache Components on Windows-hosted
servers do not consistently escape backslashes in route segments before constructing incremental-cache
paths. In packages/next/src/shared/lib/router/utils/escape-path-delimiters.ts and
packages/next/src/server/lib/incremental-cache/file-system-cache.ts, a remote request can supply encoded
Windows path separators that traverse outside the intended cache root and expose private build data,
including the server-reference-manifest encryption key. Disclosure of that key can enable remote code
execution in the affected application. This issue is fixed in versions 15.5.24 and 16.3.3.
(CVE-2026-75604)

Solution

Update the next library and its related packages to version 15.5.24 or later.
