The user-invoked bridge installs a persistent user daemon, exposes a LAN listener, and opens a relay to a package-controlled remote endpoint. The relay can forward requests to the local bridge. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-13T03:55:10.161Z - **Finished:** 2026-08-13T03:56:15.491Z - **Download time:** 250 ms - **Static scan time:** 1114 ms - **AI review time:** 63965 ms - **Total time:** 65330 ms ## Security analysis ### Published attack-surface review - **Summary:** The user-invoked bridge installs a persistent user daemon, exposes a LAN listener, and opens a relay to a package-controlled remote endpoint. The relay can forward requests to the local bridge. - **Trigger:** Running claude-codex-wechat start (or the default CLI command). - **Impact:** A compromised or unauthorized relay client could access the local bridge and its configured Claude/Codex capabilities. - **Evidence paths:** package.json, dist/server/cli.js, dist/mcp/mediaServer.js, dist/mcp/scripts/douyin-download.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-13T03:56:15.491Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent AI-agent bridge with remote request forwarding. - **Rationale:** The static malicious finding is not supported: base64 handling is transport/data encoding, not execution, and there is no install-time hook. The explicit-user persistent relay bridge remains a material capability risk requiring a warning. - **Files touched:** ~/.claude-codex-wechat/config.json, ~/Library/LaunchAgents/com.claude-codex-wechat.plist, ~/.config/systemd/user/claude-codex-wechat.service - **Network endpoints:** wss://wechat.style520.com/agent, https://registry.npmmirror.com/claude-codex-wechat/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** User-invoked start installs a persistent launchd/systemd user service., Daemon listens on 0.0.0.0 and starts a default remote relay tunnel., Relay forwards received requests to the local bridge and returns responses., Explicit upgrade command runs global npm install. - **Evidence against:** No install/preinstall/postinstall hook; only prepublishOnly is declared., No eval, Function, dynamic code import, or decoded-payload execution found., Douyin download writes only the user-selected/download output file. ## Public findings ### 1.
