AI Security Review

scanned 7d ago · by lpm-firewall-ai

The shared default credentials and automatic tunnel startup create an unsafe remote-control exposure despite the package's stated remote-access purpose. This warrants a warning; the inspected source does not establish malicious intent or direct command execution.

Static reason

No blocking static signals were detected.

Trigger

Plugin startup, unless tunnel startup is explicitly disabled or replaced with configured credentials.

Impact

A remote caller with the published defaults could access relay functions and submit prompts to the local agent; available agent tools may allow consequential local actions.

Mechanism

The tunnel forwards traffic to the local relay, which authenticates requests with the default token and forwards prompt requests to the session controller.

AI rationale

Evidence

Network endpoints2

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The plugin defines a built-in relay token and uses it when no saved token is available.
The relay accepts that token from a request and exposes RPC routes through the tunnel.
A built-in tunnel token is used by default, and the tunnel starts unless explicitly disabled.
The RPC prompt route forwards remote text to the local session controller.

50 * - `GET /api/dsh-remote/stream?session=<id>`：SSE，`event:` 是 durable 事件、

51 * `frame:` 是流式帧

53 * 选 SSE 而不是 WebSocket：手机 WebView 里 EventSource 是原生 API，断线自动重连

54 * 是浏览器内建的；WS 要自己写心跳与退避。Cloudflare 隧道对 SSE 的支持与普通

57 * ## ⚠️ 丢帧是安全的（实测结论）

59 * 手机端 `ClientAssistantStream.acceptFrame()` 遇到不连续的帧返回

60 * `{ type: 'rebaseline' }`，消费点是 `events.restart()` —— 即重连重拉基线。

61 * 而 **host 侧的帧永不丢**（进程内事件），重连后从 baseline 能补齐全部已生成内容。

62 * 所以这条通道可以做成 best-effort，不必自己设计序号补洞。
