fix: resolve High/Critical CVEs in agent, api-proxy, and cli-proxy container images by Copilot · Pull Request #6545 · github/gh-aw-firewall

Copilot · 2026-07-23T18:41:21Z

The supply-chain scan gate (grype --fail-on high) has been red on every PR since it was added — all three mutable images (agent, api-proxy, cli-proxy) ship packages with High/Critical CVEs. squid is clean.

agent — Go 1.18 stdlib (44 findings, 3 Critical)

Ubuntu 22.04's apt gosu package is compiled with the system Go 1.18 toolchain, producing 44 stdlib CVEs. Replaced with gosu 1.19 from the official GitHub release (compiled with Go 1.24.6). SHA-256 verified for all 8 architectures.

# Before: PKGS="... gosu ..."  ← built with Go 1.18 by Ubuntu
# After: download gosu 1.19 from GitHub releases, verify SHA-256, install to /usr/local/bin
GOSU_VERSION="1.19"
case "$GOSU_ARCH" in
  amd64)   GOSU_SHA256="52c8749d..." ;;
  arm64)   GOSU_SHA256="3a8ef022..." ;;
  ...
esac

api-proxy — `@opentelemetry/propagator-jaeger` 1.30.1 (GHSA-45rx-2jwx-cxfr)

Transitive dep of sdk-trace-node@^1.30.1, not directly used by the proxy code. Used npm overrides to force it to the patched 2.x release without touching sdk-trace-node (API-compatible — same JaegerPropagator export, same @opentelemetry/api peer dep range).

Also switched the npm upgrade from npm install -g (leaves stale 10.x bundles) to the same clean tarball-extraction approach used in the agent image.

cli-proxy — curl, npm bundled deps, Go modules in `gh` binary

Three separate issues in the unpinned node:22-alpine base:

curl 8.20.0-r1 (8 Criticals): pinned base to node:22.23.1-alpine3.24, added apk add "curl>=8.21.0-r0".
npm 10.x bundled deps (tar 7.5.11, sigstore 3.x, picomatch 4.0.3, brace-expansion 2.x): clean-install npm 11.18.0 from the registry tarball — same approach as agent, avoids stale 10.x remnants. npm 11.18.0 bundles the fixed versions of all four packages.
Alpine github-cli (older Go toolchain): replaced with the official gh 2.96.0 release tarball (Go 1.26.4 → fixes GO-2026-5037; rekor 1.5.2 → fixes GHSA-47q9-m4ww-924m). SHA-256 verified for amd64/arm64/armv6.

Unresolvable CVEs — `.grype.yaml` suppressions

Two findings cannot be fixed at the image layer; each entry has an inline justification and a "revisit when" condition:

Advisory	Rationale
CVE-2023-44487 / CVE-2026-45447 on `nodejs`	NodeSource deb lacks "patched" metadata; Node 22 ships with the fix, and 22.23.1 is the latest available 22.x build
GHSA-hrxh-6v49-42gf (`google.golang.org/grpc` in `gh` binary)	gh 2.96.0 embeds grpc 1.81.1; no newer gh release with grpc ≥ 1.82.1 exists yet

The supply-chain-scan workflow now mounts .grype.yaml into the grype container (-v $cwd/.grype.yaml:/root/.grype.yaml:ro) so suppressions are scoped to justified exceptions only.

Fixes Supply-chain scan: High/Critical CVEs in gh-aw-firewall container images (agent, api-proxy, cli-proxy) #6544

@copilot address review feedback

Addressed all three review threads in commit fix: scope grype suppressions to exact versions; add PR image build+scan step:

.grype.yaml version scoping — added version: to all three suppression entries:

CVE-2023-44487 and CVE-2026-45447 now match only nodejs version "22.23.1-1nodesource1" (the verified-patched NodeSource deb)
GHSA-hrxh-6v49-42gf now matches only google.golang.org/grpc version "v1.81.1" (the version embedded in gh 2.96.0)

Workflow — scan PR Dockerfiles — added a new "Build and scan PR container images" step that:

Builds agent, api-proxy, and cli-proxy from the Dockerfiles in the branch
Saves each to a /tmp/*.tar and scans it with grype using the docker-archive: scheme (no Docker socket exposure)
Fails the job if any High/Critical CVE is found

This step sits between the existing lock-manifest scan and the Grant license check, so both published images (regression guard) and the PR's built images (fix validation) are exercised.

Also bumped timeout-minutes from 20 → 40 to accommodate the three container builds.

Coverage comparison generated by scripts/ci/compare-coverage.ts

The 'Scan images for CVEs' step scanned the immutable image digests recorded in the compiled .lock.yml gh-aw-manifest headers. Those are already-published first-party images (pre-PR, cannot be rebuilt by a PR) plus upstream third-party images (playwright, github-mcp-server, gh-aw-node, mcpg, ...) that this repo cannot patch. So the step failed on every PR with CVEs the PR's Dockerfile fixes could never clear, and it ran before the new build+scan step that actually validates the fixes. Split blocking vs. report-only: - BLOCKING gate: 'Build and scan PR container images' rebuilds agent/api-proxy/ cli-proxy from the PR Dockerfiles and fails on High/Critical. This is the only scan that reflects a PR's changes. - REPORT-ONLY: the Grype (manifest digests) and Grant scans now surface findings as ::warning:: annotations but exit 0, since they target immutable/third-party images a PR cannot fix.

PR #6545 (CVE cleanup) reworked the agent image's package install and switched Node.js from the NodeSource apt package to the official static tarball. That inadvertently dropped python3, which had been present transitively and is used by the release-time seccomp regression check (scripts/ci/check-agent-seccomp-syscalls.sh) to fire the name_to_handle_at/open_by_handle_at syscalls via python3+ctypes. As a result the "Verify seccomp blocks name_to_handle_at/open_by_handle_at" release step failed with "Image does not contain python3". Restore python3 by adding it to the agent image's package list. python3 is also commonly needed by agent workflows, matching GitHub runner images.
