SCA: security update for github.com/envoyproxy/gateway (GHSA-cxpq-8v7q-cg56)

medium Tenable Cloud Security Plugin ID 444801

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, getFileFromGZ in internal/wasm/httpfetcher.go calls
io.ReadAll on a gzip.Reader without limiting decompressed output when a tenant-controlled
EnvoyExtensionPolicy.spec.wasm[].code.http.url points to a reachable compressed Wasm payload. The 256 MiB
compressed-input cap does not constrain the expanded size, no operator Wasm URL allowlist exists, and the
optional sha256 check occurs only after decompression, so a comparatively small gzip stream can force a
multi-gigabyte allocation in the shared controller. The resulting out-of-memory termination restarts the
controller, re-reconciles the persistent custom resource, and can create a persistent cross-tenant
control-plane outage. This issue is fixed in versions 1.7.4 and 1.8.1. (CVE-2026-53716)

Solution

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