## Security analysis

### Published attack-surface review

- **Summary:** A user-started daemon persists as a user service and opens a relay tunnel to a package-default third-party host. The relay forwards requests to the local bridge, which can drive configured Claude/Codex tooling and send selected files through WeChat.

- **Trigger:** User runs \`claude-codex-wechat start\` and configures/binds the bridge.

- **Impact:** Compromise or misuse of relay/WeChat access could enable remote use of the local AI-agent bridge and transfer of selected files.

- **Evidence paths:** package.json, dist/server/cli.js, dist/mcp/mediaServer.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T03:06:59.876Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Persistent relay-backed remote agent bridge with file-send capability.

- **Rationale:** The scanner’s claimed remote decode-and-execute chain is unsupported: base64 uses are data handling, and no dynamic code execution was found. The package nevertheless provides explicit persistent remote AI-agent control and file-transfer capabilities, warranting a warning.

- **Files touched:** ~/.claude-codex-wechat/config.json, ~/Library/LaunchAgents/com.claude-codex-wechat.plist, ~/.config/systemd/user/claude-codex-wechat.service

- **Network endpoints:** wss://wechat.style520.com/agent, http://127.0.0.1:8787

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** Explicit \`start\` command installs a persistent user service., Default relay connects to \`wss://wechat.style520.com/agent\`., Relay forwards requests to local bridge API., MCP tool can send a caller-selected file path to WeChat.

- **Evidence against:** No install/preinstall/postinstall hook; only prepublishOnly build., No eval, Function, or decoded remote-code execution found., Persistence is triggered by the user-invoked CLI \`start\`, not package installation.
