AI Security Review

scanned 1d ago · by lpm-firewall-ai

The package is a user-invoked WeChat-to-Claude/Codex bridge daemon with broad local agent-control capability. The risk is exposed unauthenticated local/LAN/relay administration of Codex or Claude sessions, not confirmed malware behavior.

Static reason

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

Trigger

User runs claude-codex-wechat start or __daemon via installed service.

Impact

Remote or LAN access to the daemon could drive local Claude/Codex sessions and alter bridge/session state under the user's account.

Mechanism

unauthenticated bridge daemon controlling local AI CLI processes

Attack narrative

On explicit start, the CLI installs/starts a persistent daemon and listens on all interfaces. The daemon exposes routes for WeChat setup, filesystem browsing of directories, relay tunneling, and Claude/Codex session creation/attachment; it can spawn local AI CLIs and patch their session metadata. This is package-aligned but creates a real unresolved control-plane exposure because no auth middleware was visible.

Rationale

Static inspection does not confirm malware or remote decode-and-execute behavior, but the package exposes powerful unauthenticated AI-agent control and persistence when invoked. That warrants warning rather than publish blocking.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for block

dist/server/cli.js exposes a Fastify daemon on 0.0.0.0:8787 with admin routes and no visible auth middleware.
dist/server/cli.js can spawn local claude/codex processes and codex app-server from daemon/API-driven sessions.
dist/server/cli.js writes user service files: ~/Library/LaunchAgents/com.claude-codex-wechat.plist or ~/.config/systemd/user/claude-codex-wechat.service.
dist/server/cli.js can create a relay auth token and connect to wss://wechat.style520.com/agent to proxy local daemon traffic.
dist/server/cli.js mutates ~/.claude and ~/.codex session metadata/index files for resume integration.

Evidence against

package.json has no install-time lifecycle hook; prepublishOnly is publish-side only.
The bin entrypoint only runs when user invokes claude-codex-wechat.
Flagged fetch/decrypt block is a WeChat media downloader writing attachments, not dynamic code execution.
Network endpoints align with package purpose: WeChat bridge, relay tunnel, and update check.
No eval/vm/Function or decoded payload execution found in inspected CLI source.
