Config injection prevention:
- Add FQDN validation for domain names (RFC 1123) in Register/Update —
rejects newlines, spaces, shell metacharacters that could inject into
HAProxy/dnsmasq configs
- Add backend address validation (valid host:port format, valid IP or
hostname, port 1-65535). DNS-only backends allow bare IPs.
- Add header key/value validation — keys must be HTTP token chars only,
values must not contain newlines or NULs
- Add WireGuard peer name validation (alphanumeric + hyphens + underscores)
- Add defense-in-depth domain validation in certbot Provision()
Secrets protection:
- Remove ?raw=true bypass on GET /api/v1/secrets — secrets are now always
redacted in API responses regardless of query parameters
- Update test to verify redaction cannot be bypassed
NATS authentication:
- Generate random auth token on first startup, store in secrets.yaml
- Pass token to embedded NATS server via Authorization option
- Internal client connects with the same token
- External NATS clients (Wild Cloud) must now authenticate
Security headers:
- Add X-Content-Type-Options: nosniff
- Add X-Frame-Options: DENY
- Add Cache-Control: no-store
Split /api/v1/state into dedicated resource endpoints:
- /api/v1/operator, /api/v1/central-domain
- /api/v1/ddns/config, /api/v1/dns/settings
- /api/v1/dhcp/config (moved from /dnsmasq/dhcp/)
- /api/v1/nftables/config, /api/v1/haproxy/routes
Each page now talks to its own resource instead of deep-merging
a blob. Removes useConfig hook, CentralState type, and legacy
config methods.
Fix config endpoint to return wrapped { configured, config } response
that the web UI expects. Fix services handler to return stored version
with defaults applied.
New tests:
- GetGlobalConfig: wrapped response, empty/not-configured case
- GetGlobalSecrets: leaf redaction preserves structure, raw mode
- UpdateGlobalConfig: write and verify
- CloudflareVerify: no-token case
- Services: register, list, get, update, deregister, TCP passthrough
defaults, validation errors
15 new test cases, all passing.
