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
