AI Security Review

scanned 7d ago · by lpm-firewall-ai

The package’s shared fallback token and default tunnel startup create a real remote-control risk for an intended remote desktop feature. The source does not establish a separate malicious payload or attacker activity, so this warrants a warning rather than a block.

Static reason

No blocking static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Plugin startup with automatic tunneling enabled, which is the default; the user can instead disable it in configuration.

Impact

This creates a conditional remote-control path into the local agent and the actions available to it.

Mechanism

A shared token embedded in the package is used for unpaired installs, and matching requests are routed to local RPC actions, including agent prompts.

AI rationale

Evidence

lib/index.js

Network endpoints1

dsh-remote.jiulingssh.xyz

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Unpaired installs fall back to the access token embedded in the package.
The relay authorizes requests by comparing the supplied token with its configured token.
The plugin starts the tunnel by default unless configuration disables it, using a built-in tunnel credential when no override is set.
Authorized RPC requests reach local session actions, including submitting caller-provided text to the local agent.

Evidence against

Remote access is the package’s stated purpose, and configuration can disable automatic tunnel startup; the exposed default appears to be an insecure product design rather than evidence of a separate payload.
