medium Tenable Self-Hosted Container Security Plugin ID 477825

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, 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. (CVE-2026-118656)

Solution

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