+
+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

+### 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`
+

+summary: "LINE Messaging API plugin setup, config, and usage"

+  - You want LINE-specific message options
+---
+
+# LINE (plugin)
+
+LINE connects to Clawdbot via the LINE Messaging API. The plugin runs as a webhook
+receiver on the gateway and uses your channel access token + channel secret for
+authentication.
+
+Status: supported via plugin. Direct messages, group chats, media, locations, Flex
+messages, template messages, and quick replies are supported. Reactions and threads
+are not supported.
+
+## Plugin required
+
+Install the LINE plugin:
+
+```bash
+clawdbot plugins install @clawdbot/line
+```
+
+Local checkout (when running from a git repo):
+
+```bash
+clawdbot plugins install ./extensions/line
+```
+
+## Setup
+
+1) Create a LINE Developers account and open the Console:
+   https://developers.line.biz/console/
+2) Create (or pick) a Provider and add a **Messaging API** channel.
+3) Copy the **Channel access token** and **Channel secret** from the channel settings.
+4) Enable **Use webhook** in the Messaging API settings.
+5) Set the webhook URL to your gateway endpoint (HTTPS required):
+
+```
+https://gateway-host/line/webhook
+```
+
+The gateway responds to LINE’s webhook verification (GET) and inbound events (POST).
+If you need a custom path, set `channels.line.webhookPath` or
+`channels.line.accounts.<id>.webhookPath` and update the URL accordingly.
+
+## Configure
+
+Minimal config:
+
+```json5
+{
+  channels: {
+    line: {
+      enabled: true,
+      channelAccessToken: "LINE_CHANNEL_ACCESS_TOKEN",
+      channelSecret: "LINE_CHANNEL_SECRET",
+      dmPolicy: "pairing"
+    }
+  }
+}
+```
+
+Env vars (default account only):
+
+- `LINE_CHANNEL_ACCESS_TOKEN`
+- `LINE_CHANNEL_SECRET`
+
+Token/secret files:
+
+```json5
+{
+  channels: {
+    line: {
+      tokenFile: "/path/to/line-token.txt",
+      secretFile: "/path/to/line-secret.txt"
+    }
+  }
+}
+```
+
+Multiple accounts:
+
+```json5
+{
+  channels: {
+    line: {
+      accounts: {
+        marketing: {
+          channelAccessToken: "...",
+          channelSecret: "...",
+          webhookPath: "/line/marketing"
+        }
+      }
+    }
+  }
+}
+```
+
+## Access control
+
+Direct messages default to pairing. Unknown senders get a pairing code and their
+messages are ignored until approved.
+
+```bash
+clawdbot pairing list line
+clawdbot pairing approve line <CODE>
+```
+
+Allowlists and policies:
+
+- `channels.line.dmPolicy`: `pairing | allowlist | open | disabled`
+- `channels.line.allowFrom`: allowlisted LINE user IDs for DMs
+- `channels.line.groupPolicy`: `allowlist | open | disabled`
+- `channels.line.groupAllowFrom`: allowlisted LINE user IDs for groups
+- Per-group overrides: `channels.line.groups.<groupId>.allowFrom`
+
+LINE IDs are case-sensitive. Valid IDs look like:
+
+- User: `U` + 32 hex chars
+- Group: `C` + 32 hex chars
+- Room: `R` + 32 hex chars
+
+## Message behavior
+
+- Text is chunked at 5000 characters.
+- Markdown formatting is stripped; code blocks and tables are converted into Flex
+  cards when possible.
+- Streaming responses are buffered; LINE receives full chunks with a loading
+  animation while the agent works.
+- Media downloads are capped by `channels.line.mediaMaxMb` (default 10).
+
+## Channel data (rich messages)
+
+Use `channelData.line` to send quick replies, locations, Flex cards, or template
+messages.
+
+```json5
+{
+  text: "Here you go",
+  channelData: {
+    line: {
+      quickReplies: ["Status", "Help"],
+      location: {
+        title: "Office",
+        address: "123 Main St",
+        latitude: 35.681236,
+        longitude: 139.767125
+      },
+      flexMessage: {
+        altText: "Status card",
+        contents: { /* Flex payload */ }
+      },
+      templateMessage: {
+        type: "confirm",
+        text: "Proceed?",
+        confirmLabel: "Yes",
+        confirmData: "yes",
+        cancelLabel: "No",
+        cancelData: "no"
+      }
+    }
+  }
+}
+```
+
+The LINE plugin also ships a `/card` command for Flex message presets:
+
+```
+/card info "Welcome" "Thanks for joining!"
+```
+
+## Troubleshooting
+
+- **Webhook verification fails:** ensure the webhook URL is HTTPS and the
+  `channelSecret` matches the LINE console.
+- **No inbound events:** confirm the webhook path matches `channels.line.webhookPath`
+  and that the gateway is reachable from LINE.
+- **Media download errors:** raise `channels.line.mediaMaxMb` if media exceeds the
+  default limit.

+### 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.
