Bump step-security/harden-runner from 2.16.0 to 2.19.0

[dependabot]

Bumps step-security/harden-runner from 2.16.0 to 2.19.0.

Release notes

Sourced from step-security/harden-runner's releases.

v2.19.0

What's Changed

New Runner Support

Harden-Runner now supports Depot, Blacksmith, Namespace, and WarpBuild runners with the same egress monitoring, runtime monitoring, and policy enforcement available on GitHub-hosted runners.

Automated Incident Response for Supply Chain Attacks

• Global block list: Outbound connections to known malicious domains and IPs are now blocked even in audit mode.
• System-defined detection rules: Harden-Runner will trigger lockdown mode when a high risk event is detected during an active supply chain attack (for example, a process reading the memory of the runner worker process, a common technique for stealing GitHub Actions secrets).

Bug Fixes

Windows and macOS: stability and reliability fixes

Full Changelog: step-security/harden-runner@v2.18.0...v2.19.0

v2.18.0

What's Changed

Global Block List: During supply chain incidents like the recent axios and trivy compromises, StepSecurity will add known malicious domains and IP addresses (IOCs) to a global block list. These will be automatically blocked, even in audit mode, providing immediate protection without requiring any workflow changes.

Deploy on Self-Hosted VM: Added deploy-on-self-hosted-vm input that allows the Harden Runner agent to be installed directly on ephemeral self-hosted Linux runner VMs at workflow runtime. This is intended as an alternative when baking the agent into the VM image is not possible.

Full Changelog: step-security/harden-runner@v2.17.0...v2.18.0

v2.17.0

What's Changed

Policy Store Support

Added use-policy-store and api-key inputs to fetch security policies directly from the StepSecurity Policy Store. Policies can be defined and attached at the workflow, repo, org, or cluster (ARC) level, with the most granular policy taking precedence. This is the preferred method over the existing policy input which requires id-token: write permission. If no policy is found in the store, the action defaults to audit mode.

v2.16.1

What's Changed

Enterprise tier: Added support for direct IP addresses in the allow list Community tier: Migrated Harden Runner telemetry to a new endpoint

Note

Low Risk
Low risk CI-only change updating the pinned step-security/harden-runner action version in workflows; potential impact is limited to GitHub Actions runner hardening behavior during builds.

Overview
Updates CI workflows to use step-security/harden-runner v2.19.0 (new pinned commit) for both unit tests (go.yml) and linting (golangci-lint.yml), keeping the existing egress-policy: audit configuration.
