NewCVE-2026-118656 (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, sanitizeURI checks only the first two bytes of a redirect target before deciding whether it begins with an absolute-path separator pair. When AddTrailingSlash or RemoveTrailingSlash is configured with a redirect status, a slash, TAB, separator path form can evade the guard, be emitted in the Location header, and be normalized by a browser into an attacker-controlled host. This issue is fixed in 4.16.0 and 5.4.0.
