Sustainment refresh — 2026-10-21

Why now

govulncheck reported 21 called vulnerabilities against main (Go 1.26.5 toolchain + third-party modules), all published since v1.9.1. The CI and Release workflows gate on it.

Applied bumps

Kind Name Before After
tool Go toolchain (go.mod, go.work) 1.26.5 1.27.3
tool Dockerfile build image golang:1.26.5 golang:1.27.3
tool golangci-lint CI pin v2.11.4 v2.15.0 (go1.27 support since v2.13.0)
lib golang.org/x/net v0.57.0 v0.61.0
lib go.opentelemetry.io/otel (+ metric, sdk, trace, otlptrace exporters) v1.44.0 v1.47.0
lib otelhttp v0.69.0 v0.72.0
lib google.golang.org/grpc v1.82.1 v1.84.0
lib x/crypto, x/sys, x/text, protobuf, genproto, grpc-gateway, testify — latest patch/minor

vendor/ regenerated with go work vendor.

Go 1.26 → 1.27 is a minor-version bump — human review per repo policy. Go 1.26.10 would also have cleared every stdlib advisory if we'd rather stay on 1.26.

The newer golangci-lint goconst flagged repeated literals in internal/config/validation_test.go; hoisted into constants, no behaviour change.

Vulnerabilities

Scanner Before After
govulncheck (called) 21 0
govulncheck (required modules only) 6 1 — GO-2026-5932 x/crypto/openpgp, no fix, package not imported

Checks (Go 1.27.3, tools built with go1.27)

  • ✅ go build ./..., go vet ./...
  • ✅ go test -race ./... — 108 passed in 7 packages
  • ✅ govulncheck ./... — 0 called
  • ✅ golangci-lint run ./... (v2.15.0) — 0 issues
  • ✅ gofmt -l — clean
  • ⚠️ Docker image not built locally — CI will.

Release

Second commit cuts v1.9.2 + chart 1.10.2 (appVersion → 1.9.2). After merge: tag v1.9.2 and chart-v1.10.2.

Clears the 21 called vulnerabilities govulncheck reported against the
module (16 standard library, 5 third-party).

Go toolchain 1.26.5 -> 1.27.3 covers the standard-library advisories
(net/http, crypto/tls, crypto/x509, html/template, encoding/xml,
encoding/asn1, net/url, net/textproto). golang.org/x/net 0.57.0 -> 0.61.0,
otel 1.44.0 -> 1.47.0 (otelhttp 0.69.0 -> 0.72.0) and grpc 1.82.1 ->
1.84.0 clear the rest. The build image pin follows the toolchain.

golangci-lint CI pin v2.11.4 -> v2.15.0: go1.27 support landed in
v2.13.0. Its goconst check flagged repeated literals in a config test;
hoisted into constants, no behaviour change.

govulncheck: 21 called vulnerabilities -> 0.

Security-only release: the dependency refresh in the previous commit (Go
1.27.3, 21 called vulnerabilities cleared).

Chart appVersion follows to 1.9.2 so the default image tag pulls the
patched build instead of the vulnerable 1.9.1 one.
