Summary

  • Add apk upgrade --no-cache to final image stages in Dockerfile and Dockerfile.dev
  • Bumps zlib from 1.3.1-r2 to 1.3.2-r0, resolving CVE-2026-22184 (critical buffer overflow in untgz)
  • Dockerfile.base already had apk upgrade in the chef stage

Test plan

  • Verify mc Docker publish workflow passes Trivy scan
  • Confirm final image runs correctly (docker run + healthcheck)

Add apk upgrade to final image stages so zlib 1.3.1-r2 → 1.3.2-r0,
fixing the critical buffer overflow CVE flagged by Trivy.
