Bumps step-security/harden-runner from 2.18.0 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
