Echo: next: security update to 15.5.21

high Tenable Self-Hosted Container Security Plugin ID 460602

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, a rewrites() or redirects() rule that builds its external destination hostname
from request-controlled input can be pointed at an arbitrary hostname, regardless of the rule's hostname
suffix. For a rewrite, Next.js proxies the request to that arbitrary host and serves the response from the
application's origin, leading to Server-Side Request forgery. A redirects() rule configured this way is
vulnerable to an Open Redirect. This issue has been fixed in versions 15.5.21 and 16.2.11.
(CVE-2026-64645)

Solution

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