AI Security Review

scanned 7d ago · by lpm-firewall-ai

The intended pairing flow can establish per-pair credentials, but the unpaired default path starts a public tunnel with package-shared credentials and exposes agent-control RPCs. This is a concrete security risk, though the inspected source does not establish malicious intent or exploitation.

Static reason

No blocking static signals were detected.

Trigger

The plugin is loaded with default configuration and no paired or user-provided tunnel and relay credentials.

Impact

A party with the shared default credential may access host directory information and send prompts to the local DSH agent. The source does not establish exploitation or subsequent agent actions.

Mechanism

The plugin starts cloudflared automatically and routes to a relay whose authentication token falls back to a constant embedded in the package; the relay accepts RPC requests that list directories, create sessions, and submit prompts.

AI rationale

Evidence

lib/index.js

Network endpoints2

dsh-remote.jiulingssh.xyzpair.jiulingssh.xyz

Decision evidence

public snapshot

AI called this Suspicious at 97.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The runtime entry point is lib/index.js, and the plugin starts a tunnel by default using package fallback credentials when no override is configured.
Without a paired or local token, the relay uses a package constant for authentication; startup also logs the active relay token.
The authenticated relay exposes host directory listing and RPCs that create sessions and submit prompts to the local DSH agent.
Pairing stores server-returned tunnel and access tokens locally, providing a per-pair credential path.
The source identifies the default tunnel host and downloads cloudflared from the package's pairing host.
