SCA: security update for github.com/labstack/echo/v4, github.com/labstack/echo/v5 (GHSA-2ffq-g2xg-c22p)

medium Tenable Cloud Security Plugin ID 477796

Description

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

 - Echo is a Go web framework. Prior to 4.16.0 and 5.4.0, Context.Scheme unconditionally trusts forwarded
 scheme headers from any client. A client that reaches Echo directly over plaintext HTTP can claim an HTTPS
 scheme and bypass HTTPSRedirect because the request is treated as already secure. Separately, behind a
 TLS-terminating proxy that passes an attacker-controlled header, a claimed HTTP scheme can suppress the
 Strict-Transport-Security header even though the browser receives the response over HTTPS. The practical
 risk is reduced when a trusted proxy overwrites the headers and direct backend access is prevented, but
 the framework previously had no trusted-source configuration for this decision. This issue is fixed in
 4.16.0 and 5.4.0. (CVE-2026-118657)

Solution

Update the github.com/labstack/echo/v4 library and its related packages to version 4.16.0 or later.
