Echo: http-proxy-middleware: security update to 2.0.10

medium Tenable Cloud Security Plugin ID 463540

Description

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

- http-proxy-middleware is node.js http-proxy middleware. From 0.16.0 until 2.0.10, 3.0.6, and 4.1.0, http-
proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the
host+path implementation uses unanchored substring matching on attacker-controlled request metadata. As a
result, a crafted Host header that is only a superstring match for a configured host+path key can still
route a request to an unintended backend. This vulnerability is fixed in 2.0.10, 3.0.6, and 4.1.0.
(CVE-2026-55602)

Solution

Update the http-proxy-middleware library and its related packages to version 2.0.10 or later.
