Summary

  • Bumps toolchain from go1.26.1 to go1.26.2, fixing 4 reachable stdlib vulnerabilities in crypto/x509 (GO-2026-4947, GO-2026-4946, GO-2026-4866) and crypto/tls (GO-2026-4870)
  • Two Docker daemon-side vulnerabilities (GO-2026-4887 AuthZ plugin bypass, GO-2026-4883 plugin privilege off-by-one) have no upstream fix in docker/[email protected]; the CI govulncheck step now runs in JSON mode and suppresses only these two known false-positives, failing on anything unexpected
  • Adds a CLAUDE.md note to keep go.mod, the devcontainer image tag, and the govulncheck suppression list in sync on future toolchain bumps

Test Plan

  • govulncheck CI job passes (was previously failing with exit 3)
  • All other CI jobs unaffected (go test, golangci-lint, go vet, build)

🤖 Generated with Claude Code

Four standard-library vulnerabilities (GO-2026-4947, GO-2026-4946,
GO-2026-4870, GO-2026-4866) in crypto/x509 and crypto/tls are fixed
by upgrading the toolchain from go1.26.1 to go1.26.2.

Two remaining Docker daemon-side vulnerabilities (GO-2026-4887,
GO-2026-4883) have no upstream fix available (docker/[email protected]
is the latest release). govulncheck has no native ignore flag, so the
CI step now runs govulncheck in JSON mode and suppresses only these
two known false-positives, failing on anything unexpected.

Also adds a CLAUDE.md note to keep go.mod, the devcontainer image
tag, and the govulncheck suppression list in sync on future toolchain
bumps.
