Summary
nebula-mesh: Host advanced overrides allow YAML injection into agent config.yml
Details

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.2, internal/configgen/generator.go:86,108,119 interpolates the operator-supplied ListenHost and TunDevice fields raw into a text/template that produces the agent's config.yml. internal/web/advanced.go:20-35 accepts both with only strings.TrimSpace — no character or shape validation. Version 0.3.2 fixes the issue.
