SCA: security update for github.com/envoyproxy/gateway (GHSA-8fv2-88gg-hm7q)

medium Tenable Cloud Security Plugin ID 444809

Description

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

 - Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based
 application gateway. Prior to 1.7.4 and 1.8.1, HTTPServer.ServeHTTP in internal/wasm/httpserver.go reads
 the plain mappingPath2Cache map without synchronization while HTTPServer.Get writes the same map during
 EnvoyExtensionPolicy translation. An attacker with pod-network access to unauthenticated port 18002 and
 tenant permission to churn policies with distinct Wasm URLs can flood GET requests until a per-request
 reader overlaps a writer. Go's concurrent map read and write detection invokes runtime.throw, which the
 net/http connection recovery cannot catch, terminating the controller process and causing a timing-
 dependent, cross-tenant control-plane denial of service until Kubernetes restarts the pod. This issue is
 fixed in versions 1.7.4 and 1.8.1. (CVE-2026-53715)

Solution

Update the github.com/envoyproxy/gateway library and its related packages to version 1.7.4 or later.
