- macOS: keep custom SSH usernames in remote target. (#2046) Thanks @algal.
### Fixes
- Security: harden Tailscale Serve auth by validating identity via local tailscaled before trusting headers.
- Security: add mDNS discovery mode with minimal default to reduce information disclosure. (#1882) Thanks @orlyjamie.
- Web UI: improve WebChat image paste previews and allow image-only sends. (#1925) Thanks @smartprogrammer93.
- Security: wrap external hook content by default with a per-hook opt-out. (#1827) Thanks @mertcicekci0.
- Gateway: default auth now fail-closed (token/password required; Tailscale Serve identity remains allowed).

For threat model + hardening guidance (including `clawdbot security audit --deep` and `--fix`), see:
- `https://docs.clawd.bot/gateway/security`
## Runtime Requirements
### Node.js Version
Clawdbot requires **Node.js 22.12.0 or later** (LTS). This version includes important security patches:
- CVE-2025-59466: async_hooks DoS vulnerability
- CVE-2026-21636: Permission model bypass vulnerability
Verify your Node.js version:
```bash
node --version # Should be v22.12.0 or later
```
### Docker Security
When running Clawdbot in Docker:
1. The official image runs as a non-root user (`node`) for reduced attack surface
2. Use `--read-only` flag when possible for additional filesystem protection
3. Limit container capabilities with `--cap-drop=ALL`
Example secure Docker run:
```bash
docker run --read-only --cap-drop=ALL \
-v clawdbot-data:/app/data \
clawdbot/clawdbot:latest
```
## Security Scanning
This project uses `detect-secrets` for automated secret detection in CI/CD.
See `.detect-secrets.cfg` for configuration and `.secrets.baseline` for the baseline.
Run locally:
```bash
pip install detect-secrets==1.5.0
detect-secrets scan --baseline .secrets.baseline
```

@ -280,22 +280,63 @@ The Gateway multiplexes **WebSocket + HTTP** on a single port:
Bind mode controls where the Gateway listens:
- `gateway.bind: "loopback"` (default): only local clients can connect.
- Non-loopback binds (`"lan"`, `"tailnet"`, `"custom"`) expand the attack surface. Only use them with `gateway.auth` enabled and a real firewall.
- Non-loopback binds (`"lan"`, `"tailnet"`, `"custom"`) expand the attack surface. Only use them with a shared token/password and a real firewall.
Rules of thumb:
- Prefer Tailscale Serve over LAN binds (Serve keeps the Gateway on loopback, and Tailscale handles access).
- If you must bind to LAN, firewall the port to a tight allowlist of source IPs; do not port-forward it broadly.
- Never expose the Gateway unauthenticated on `0.0.0.0`.
### 0.4.1) mDNS/Bonjour discovery (information disclosure)
The Gateway broadcasts its presence via mDNS (`_clawdbot-gw._tcp` on port 5353) for local device discovery. In full mode, this includes TXT records that may expose operational details:
- `cliPath`: full filesystem path to the CLI binary (reveals username and install location)
- `sshPort`: advertises SSH availability on the host
- `displayName`, `lanHost`: hostname information
**Operational security consideration:** Broadcasting infrastructure details makes reconnaissance easier for anyone on the local network. Even "harmless" info like filesystem paths and SSH availability helps attackers map your environment.
**Recommendations:**
1. **Minimal mode** (default, recommended for exposed gateways): omit sensitive fields from mDNS broadcasts:
```json5
{
discovery: {
mdns: { mode: "minimal" }
}
}
```
2. **Disable entirely** if you don't need local device discovery:
```json5
{
discovery: {
mdns: { mode: "off" }
}
}
```
3. **Full mode** (opt-in): include `cliPath` + `sshPort` in TXT records:
```json5
{
discovery: {
mdns: { mode: "full" }
}
}
```
4. **Environment variable** (alternative): set `CLAWDBOT_DISABLE_BONJOUR=1` to disable mDNS without config changes.
In minimal mode, the Gateway still broadcasts enough for device discovery (`role`, `gatewayPort`, `transport`) but omits `cliPath` and `sshPort`. Apps that need CLI path information can fetch it via the authenticated WebSocket connection instead.
### 0.5) Lock down the Gateway WebSocket (local auth)
Gateway auth is **only** enforced when you set `gateway.auth`. If it’s unset,
loopback WS clients are unauthenticated — any local process can connect and call
`config.apply`.
Gateway auth is **required by default**. If no token/password is configured,
the Gateway refuses WebSocket connections (fail‑closed).
The onboarding wizard now generates a token by default (even for loopback) so
local clients must authenticate. If you skip the wizard or remove auth, you’re
back to open loopback.
