AI Security Review

scanned 1d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established by source inspection. The package is a user-invoked CLI/server bridge for sending Claude/Codex activity through WeChat, with expected network and process-control primitives for that purpose.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs the claude-codex-wechat CLI or related dev/publish scripts.

Impact

Can persist local bridge configuration and forward messages to user-configured WeChat/relay endpoints when explicitly run.

Mechanism

User-configured local bridge server, WeChat/relay networking, and spawning Claude/Codex commands.

Rationale

Source inspection found powerful but package-aligned runtime behavior for a Claude/Codex WeChat bridge, not unconsented lifecycle execution or remote decoded code execution. The scanner's critical label appears to be a false positive against bundled runtime primitives and a font asset.

Evidence

Network endpoints1

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.

Evidence for block

dist/server/cli.js is executable bin and exposes local Fastify API plus SSE/event handling for Claude/Codex-to-WeChat bridging.
dist/server/cli.js reads/writes package config, WeChat credentials, relay auth token, and Claude session metadata only through runtime flows.
dist/server/cli.js uses child_process spawn/execFile to launch configured Claude/Codex CLIs and relay-server, including detached local service behavior.
dist/server/cli.js references package-aligned network endpoints: WeChat baseUrl, optional relay config, GitHub release URL, localhost server/SSE routes.

Evidence against

package.json has no install/postinstall/prepare hook; prepublishOnly only runs build before publisher publish, not consumer install.
No evidence of install-time execution, import-time payload execution, or decoded remote asset execution in inspected cli bundle.
No hardcoded exfiltration host or credential harvesting beyond user-configured WeChat/relay integration paths.
High-entropy woff2 asset is a normal bootstrap icon font under dist/web/assets, not executable code.
Writes are bounded to user config/state/session bridge metadata used by the declared CLI service.
