The bridge exposes unauthenticated caller-selected command execution. - **Trigger:** Global npm installation on macOS. - **Impact:** A network client can execute commands with the installing user's environment and access. - **Evidence paths:** package.json, postinstall.js, install.sh, bridge.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T06:24:31.485Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall persistence plus network-exposed arbitrary command spawning - **Attack narrative:** On a macOS global install, postinstall invokes install.sh. The installer creates KeepAlive LaunchAgents and starts a bridge listening on all interfaces. Any WebSocket client can invoke local/exec, which passes its command array directly to spawn with the installer user's environment. This combines unconsented install-time persistence with a LAN-exposed arbitrary-command service. - **Rationale:** The package performs concrete install-time persistence and exposes arbitrary command execution over a 0.0.0.0 WebSocket listener without source-visible authentication. Its platform/global guards limit reach but do not remove the exploit path. - **Files touched:** $HOME/Library/Application Support/DexRelay/runtime, $HOME/Library/LaunchAgents/com.codexrelay.bootstrap.plist, $HOME/Library/LaunchAgents/com.codexrelay.setuphelper.plist, $HOME/Library/LaunchAgents/com.codexrelay.healthd.plist - **Network endpoints:** https://assets.dexrelay.app, 0.0.0.0:4615 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs install.sh on global macOS installs., Installer creates persistent LaunchAgents and starts them., Persistent bridge binds 0.0.0.0 and accepts local/exec., local/exec spawns caller-supplied commands without authentication. - **Evidence against:** Postinstall skips non-macOS, CI, and non-global installs., Remote asset fallback is not taken when bundled sources exist. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.js ``` ### 3.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 95.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** bridge.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = dexrelay@0.1.70 matchedIdentity = npm:ZGV4cmVsYXk:0.1.70 similarity = 0.833 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** install.sh - **Public source:** [View source]() Installer creates persistent LaunchAgents and starts them. Public source snippet (untrusted): ```text write_launch_agent() { mkdir -p "$LAUNCH_AGENTS_DIR" cat >"$BRIDGE_PLIST" < Label $BRIDGE_LABEL ProgramArguments $BIN_DIR/start-bridge.sh RunAtLoad KeepAlive ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** bridge.js - **Public source:** [View source]() local/exec spawns caller-supplied commands without authentication. Public source snippet (untrusted): ```javascript function runLocalExec(params = {}) { return new Promise((resolve) => { const command = Array.isArray(params.command) ? params.command : null; const cwd = typeof params.cwd === 'string' && params.cwd.length > 0 ? params.cwd : process.cwd(); const timeoutMs = Number.isFinite(params.timeoutMs) ?
