linkshell-cli@0.5.39
Remote terminal bridge for Claude Code / Codex / Gemini / Copilot — control from your phone
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package is not covertly malicious at install time, but it intentionally provides high-impact remote command and agent execution. The unconfirmed permission-bypass fallback is a concrete dangerous capability that warrants a warning.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs linkshell start and connects a remote client through the configured gateway.
Impact
A connected remote party can execute commands through the spawned terminal, access permitted files, and potentially cause agent tools to run without confirmation.
Mechanism
Remote terminal and agent command relay with a permission-bypass fallback.
AI rationale
The package is not covertly malicious at install time, but it intentionally provides high-impact remote command and agent execution. The unconfirmed permission-bypass fallback is a concrete dangerous capability that warrants a warning.
Evidence
src/runtime/bridge-session.tssrc/runtime/acp/claude-stream-json-client.ts
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- A remote gateway message can write directly to a local PTY and request additional terminals.
- The Claude fallback explicitly accepts remotely submitted prompts while launching Claude with permission bypass, allowing tool and shell execution without confirmation.
- The bridge also exposes remote browsing and reading of files beneath the configured home-directory root.
Evidence against
- The install hook only restores execute permissions on node-pty helper binaries.
- The remote bridge and screen-sharing features require an explicit linkshell start command.
- No self-dependency, hidden payload download, credential harvesting, or install-time agent-control mutation was found.
