NewCVE-2026-118657 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest golang-github-labstack-echo.
NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-github-labstack-echo package and not the golang-github-labstack-echo package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
