… and CVE-2026-33748 Both CVEs (CVSS 8.4 and 8.0) affect moby/buildkit < v0.28.1. Upgraded from v0.21.0 to v0.28.1. buildkit v0.28.1 requires docker/cli v29, which is incompatible with harness/nektos-act/v2 (uses removed v28 APIs). Added a replace directive to pin docker/cli to v28.0.4 at compile time while satisfying buildkit's declared dependency on v29.2.1. Verified with govulncheck: 0 vulnerabilities found in code or imported packages. AI-Session-Id: e5fffb26-30d0-4e53-aa03-bc09d36c2599 AI-Tool: claude-code AI-Model: global.anthropic.claude-sonnet-4-6
