What is GitHub Actions 2026 security roadmap?

GitHub's plan to secure Actions with lockfiles for dependencies, centralized execution policies, and immutable publishing—rolling out public previews in 3-6 months.

Not immediately—public preview first, plus evaluate mode for policies. Pinning SHAs is opt-in but recommended; expect marketplace shifts to immutable refs.

How do GitHub Actions security policies prevent supply chain attacks?

They centralize controls on workflow triggers, permissions, and events via rulesets, blocking risky runs like over-permissioned PRs across your org.
