SCA: security update for github.com/envoyproxy/gateway (GHSA-h7pq-86h8-rp5x)

medium Tenable Self-Hosted Container Security Plugin ID 444810

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, internal/wasm/imagefetcher.go follows tenant-controlled
 EnvoyExtensionPolicy spec.wasm[].code.image.url values to Docker or OCI Wasm layers, and
 extractWasmPluginBinary uses the untrusted tar-header h.Size value to allocate memory before validating
 the entry name or declared size. A small PAX or GNU tar header can therefore claim a multi-terabyte entry
 even though the surrounding LimitReader restricts only the bytes read from the stream, and no registry
 allowlist prevents a permitted tenant from selecting an attacker-controlled registry that the controller
 can reach. The allocation is attempted for every tar entry and can cause an unrecoverable Go runtime out-
 of-memory failure; because the custom resource persists, reconciliation repeatedly crash-loops the shared
 controller and causes a single-request, non-volumetric, cluster-wide control-plane denial of service. This
 issue is fixed in versions 1.7.4 and 1.8.1. (CVE-2026-53717)

Solution

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