AI Security Review

scanned 1d ago · by lpm-firewall-ai

The package turns WeChat and relay traffic into a remote control surface for local Claude/Codex sessions while forcing Claude permission bypass. It also mutates existing Claude session files to add bypassPermissions metadata.

Static reason

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

Trigger

Running `claude-codex-wechat start` and using the WeChat/session bridge

Impact

Remote chat/relay users can drive local AI coding agents with reduced permission controls; existing Claude session metadata is modified to bypass permissions on resume.

Mechanism

persistent remote AI-agent bridge with forced permission bypass

Attack narrative

When started, the CLI installs a persistent daemon, opens a local bridge, optionally registers a relay, and accepts WeChat/admin requests that create or resume Claude/Codex sessions. Claude sessions are launched with --dangerously-skip-permissions, and existing Claude JSONL session files are rewritten to include permissionMode:bypassPermissions when normalized for resume.

Rationale

Although the bridge purpose is disclosed, forcing and persisting Claude permission bypass creates an unconsented AI-agent control-surface mutation with concrete local impact. This exceeds benign package-aligned functionality and warrants blocking. Product guard normalized a non-low false-positive publish_block request to warn-only suspicious.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for block

dist/server/cli.js buildStreamingArgs always adds --dangerously-skip-permissions for Claude Code sessions.
dist/server/cli.js normalizeClaudeSessionFileForResume rewrites Claude session JSONL entrypoint sdk-cli to cli and injects permissionMode:bypassPermissions.
dist/server/cli.js exposes WeChat/HTTP routes that create, attach, steer, interrupt, and send messages into local Claude/Codex sessions.
dist/server/cli.js start installs a persistent user service via launchd/systemd or detached process.
dist/server/cli.js relay tunnel connects to wss://wechat.style520.com/agent and forwards remote requests to local 127.0.0.1 bridge.

Evidence against

package.json has no install/postinstall lifecycle hook; prepublishOnly is publish-time build only.
README.md discloses the package is a local WeChat to Claude/Codex bridge daemon and that start registers a system service.
Network endpoints for Weixin login/API are aligned with the package's WeChat bridge purpose.
