CyberRota Analysis
AI-GeneratedThe nebula-mesh control plane for Slack Nebula VPN is vulnerable due to improper validation of user-supplied `ListenHost` and `TunDevice` fields, which are directly interpolated into a configuration file without sufficient sanitization. This flaw could lead to potential code injection or misconfiguration, impacting the security and functionality of the VPN. Organizations using versions prior to 0.3.2 should prioritize upgrading to mitigate these risks.

Original NVD Description
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.
