CyberRota Analysis
AI-GeneratedThe nebula-mesh control plane for Slack Nebula VPN is vulnerable in versions 0.3.0 to before 0.5.0, where the Web UI's host-creation process disregards configured enrollment token lifetimes, allowing authenticated operators to generate bearer tokens valid for approximately 24 hours. This could lead to unauthorized access if an operator misuses their privileges. Organizations using affected versions should prioritize upgrading to version 0.5.0 to mitigate potential security risks.

Original NVD Description
nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.3.0 to before version 0.5.0, the nebula-mgmt Web UI host-creation path ignores both the server-wide enrollment_token_ttl security setting and per-network network_config.enrollment_token_ttl overrides. API host creation and token-regeneration paths use the configured TTL resolver, but POST /ui/hosts hardcodes now.Add(24 * time.Hour) for newly minted agent enrollment tokens. In deployments that intentionally reduce enrollment-token lifetime, any authenticated operator who can create a host through the Web UI can still mint a bearer enrollment token valid for about 24 hours. This issue has been patched in version 0.5.0.
