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.

Affected: Go: github.com/forgekeep/nebula-mesh

### Summary 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.

### Details Enrollment tokens are bearer credentials for the public `POST /api/v1/enroll` endpoint: possession of a valid token allows enrolling the pending host and receiving a signed Nebula certificate/config for that host. The server configuration documents a security knob for their default lifetime and per-network overrides:

- `internal/config/server.go:82` defines `EnrollmentTokenTTL` as the default lifetime for freshly minted enrollment tokens. - `internal/config/server.go:83` documents per-network overrides in `network_config` under `enrollment_token_ttl`.

The API server implements and consistently uses this resolver:

- `internal/api/server.go:77` defines `tokenTTLFor`, with precedence of per-network `enrollment_token_ttl`, then server default, then 24h fallback. - `internal/api/server.go:82` reads `network_config.enrollment_token_ttl`. - `internal/api/server.go:89` falls back to the configured server d…
