@luckydraw/cumulus@0.31.41

RLM-based CLI chat wrapper for Claude with external history context management

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The package is not malicious by source evidence, but it deliberately supplies remotely reachable high-impact agent execution capabilities. Flag as a warning so deployment requires review of gateway exposure and API-key handling.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

An authenticated gateway request or explicit CLI/TUI use starts an agent run.

Impact

Prompt-controlled agent actions can execute shell commands, modify files, and make network requests in its configured working directory.

Mechanism

Claude bypass-permission subprocess plus Bash, Write, and WebFetch tools.

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/lib/gateway.js launches Claude with --permission-mode bypassPermissions.
dist/lib/tools/bash.js exposes unrestricted bash -c execution to the agentic loop.
dist/lib/tools/write.js and web-fetch.js permit agent-directed file writes and arbitrary HTTP requests.
dist/gateway/server.js accepts authenticated remote messages that reach the execution pipeline.

Evidence against

package.json has no preinstall/install/postinstall hook; prepare only invokes husky.
dist/gateway/setup.js creates services only after explicit setup and interactive confirmation.
dist/lib/version-check.js contacts npm only for version checks; installs occur through explicit update paths.
No source evidence of covert credential harvesting, external exfiltration, or hidden payload execution.
