Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The install hook installs additional runtime dependencies under the user's PolyRouter data directory. A bundled, separately installed browser connector can import ChatGPT/OpenAI cookies to the local gateway, and the app contains opt-in MITM capability for AI-tool traffic. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-23T06:32:48.020Z - **Finished:** 2026-08-23T06:34:11.388Z - **Download time:** 1516 ms - **Static scan time:** 1420 ms - **AI review time:** 80431 ms - **Total time:** 83368 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The install hook installs additional runtime dependencies under the user's PolyRouter data directory. A bundled, separately installed browser connector can import ChatGPT/OpenAI cookies to the local gateway, and the app contains opt-in MITM capability for AI-tool traffic. - **Trigger:** npm postinstall; separately installing and using the bundled connector or enabling MITM/tray features. - **Impact:** Credential-bearing AI sessions and intercepted AI-tool requests are exposed to the local PolyRouter service; OS persistence is opt-in. - **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, app/src/mitm/server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T06:34:11.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** runtime dependency installation plus local AI-session interception/import capability - **Rationale:** Source inspection supports a dangerous credential/interception capability and install-time dependency fetching, not a concrete malicious chain. The static claim of remote payload execution was not substantiated. - **Files touched:** hooks/postinstall.js, hooks/sqliteRuntime.js, hooks/trayRuntime.js, cli.js, src/cli/tray/autostart.js, app/public/downloads/polyrouter-connector.zip, app/src/mitm/server.js - **Network endpoints:** https://registry.npmjs.org/polyrouter/latest, https://chatgpt.com/, https://openai.com/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Install hook downloads SQLite and tray dependencies into a user-writable runtime., Bundled browser connector requests ChatGPT/OpenAI cookie access and sends collected cookies to a local PolyRouter endpoint., The runtime includes privileged MITM/hosts-file interception capability for AI-tool traffic., User-selected tray mode creates OS autostart persistence. - **Evidence against:** No source evidence of sending harvested cookies or environment secrets to a non-local attacker endpoint., Postinstall invokes package-aligned runtime setup, not AI-agent configuration mutation., Autostart is reached only after the user selects the Hide-to-Tray menu action., The reported remote download-and-execute finding is not supported by cli.js; it only checks npm registry metadata. ## Affected versions and remediation This report applies to polyrouter@1.0.17. - Review the evidence and your use of polyrouter@1.0.17 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.
