linkshell-cli@0.5.38
Remote terminal bridge for Claude Code / Codex / Gemini / Copilot — control from your phone
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo concrete malicious installation chain, covert endpoint, self-dependency, or unconsented broad agent-control mutation was found. The explicit remote-agent fallback still creates a significant dangerous capability that warrants a warning.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user starts the LinkShell bridge with agent features and pairs a remote client.
Impact
A paired or compromised remote client could cause local agent tools to run and receive shell-history data.
Mechanism
Remote bridge forwarding to an unprompted Claude shell-capable fallback.
AI rationale
No concrete malicious installation chain, covert endpoint, self-dependency, or unconsented broad agent-control mutation was found. The explicit remote-agent fallback still creates a significant dangerous capability that warrants a warning.
Evidence
src/runtime/acp/claude-stream-json-client.tssrc/runtime/bridge-session.ts~/.zsh_history~/.bash_history
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The package exposes a post-install hook.
- Its Claude fallback explicitly permits remotely submitted prompts to run tools, including a shell, without confirmation.
- A connected remote client can request shell history, which is returned through the bridge.
- The explicit upgrade command performs a global install of the latest package release.
Evidence against
- The post-install script only changes execute permissions on known node-pty helper paths; it has no network or agent-config action.
- The remote bridge and agent features require an explicit runtime command, not package installation.
- No runtime dependency on linkshell-cli itself was found.
- No fixed covert exfiltration endpoint or install-time secret harvesting was found.
