Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation fetches runtime packages into a user-writable directory and enables a downloaded tray binary. A bundled Chrome extension intentionally imports selected provider cookies into the local gateway after confirmation. - **Trigger:** npm postinstall; connector installation and user-approved session import - **Impact:** A compromised future runtime dependency or tray package could execute outside the immutable npm package directory. - **Evidence paths:** package.json, hooks/postinstall.js, hooks/sqliteRuntime.js, hooks/trayRuntime.js, cli.js, src/cli/tray/autostart.js, app/public/downloads/polyrouter-connector.zip - **Review source:** ai\_review - **Reviewed:** 2026-08-12T19:24:09.987Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time runtime dependency bootstrap and local cookie import - **Rationale:** This is a risky staged runtime-payload design, not confirmed malware from the inspected source. Warn so users are informed of install-time downloads and executable binary bootstrapping. - **Files touched:** ~/.polyrouter/runtime/package.json, ~/.polyrouter/runtime/node\_modules, app/public/downloads/polyrouter-connector.zip - **Network endpoints:** https://registry.npmjs.org/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** postinstall runs code that installs runtime dependencies into ~/.polyrouter/runtime., Lifecycle installs systray2 and marks its downloaded platform binary executable on macOS/Linux., Bundled connector can collect OpenAI/ChatGPT cookies and send them to a local PolyRouter origin after a user confirmation. - **Evidence against:** No source evidence of credential exfiltration to a remote host was found., Autostart is only enabled from the CLI's explicit “Hide to Tray” choice., The connector restricts requests to http localhost/127.0.0.1 and prompts before session import. ## Affected versions and remediation This report applies to polyrouter@1.0.14. - Review the evidence and your use of polyrouter@1.0.14 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
