PTY session management, WebSocket streaming, and REST API server for Claude Code conversations

AI Security Review

scanned 8d ago · by lpm-firewall-ai

No confirmed malicious install-time or import-time attack surface. Risky primitives are tied to the stated streamer CLI/server purpose and user-invoked operations.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

npm install runs postinstall chmod only; runtime actions require threadbase-streamer CLI/server use

Impact

No confirmed credential theft, exfiltration, persistence, or unconsented foreign AI-agent control-surface mutation

Mechanism

package-aligned PTY streaming, local API server, cache/config management, and optional updater

Rationale

Static inspection shows a Claude/Codex conversation streamer with expected child_process, filesystem, WebSocket, and updater code, while the lifecycle hook only repairs node-pty helper permissions. No unconsented lifecycle mutation of Claude/Codex/MCP control surfaces, exfiltration, remote code execution, or destructive behavior was found.

Evidence

package.jsondist/index.cjsdist/cli.cjsdist/seed-claude-config.cjsnode-pty/prebuilds/<platform-arch>/spawn-helper~/.threadbase/server.yaml~/.threadbase/cache/cache.dbCLAUDE_CONFIG

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for block

package.json postinstall executes node -e chmod on node-pty prebuild spawn-helper
dist/seed-claude-config.cjs can write a CLAUDE_CONFIG file when explicitly run
dist/index.cjs spawns claude/codex PTYs and uses --permission-mode acceptEdits
dist/cli.cjs contains user-invoked updater/service controls

Evidence against

postinstall only chmods node-pty's platform spawn-helper, no network or foreign agent config writes
main/import files define APIs; server/PTY behavior starts via CLI serve or API calls
Claude/Codex session reads are package-aligned conversation streaming/cache behavior
seed-claude-config requires direct execution and CLAUDE_CONFIG env, not lifecycle-triggered
GitHub update download is user/config-driven and verifies manifest sha256
