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. On installation, the package creates a user-writable runtime directory and runs npm to obtain additional code, including a native SQLite module and a tray package. This is an automatic supply-chain expansion outside the package tarball. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-09-13T22:51:05.226Z - **Finished:** 2026-09-13T22:52:41.817Z - **Download time:** 1518 ms - **Static scan time:** 26518 ms - **AI review time:** 68554 ms - **Total time:** 96591 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:** On installation, the package creates a user-writable runtime directory and runs npm to obtain additional code, including a native SQLite module and a tray package. This is an automatic supply-chain expansion outside the package tarball. - **Trigger:** npm installation triggers postinstall. - **Impact:** Later-installed dependency code and a tray binary can run from the user's data directory. - **Evidence paths:** package.json, hooks/postinstall.js, hooks/sqliteRuntime.js, hooks/trayRuntime.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T22:52:41.817Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-created runtime project followed by npm installs and executable permission changes. - **Rationale:** The automatic postinstall downloader and executable-binary setup are a concrete unresolved supply-chain risk. The inspected sources do not establish malicious intent or a direct credential/data theft path. - **Files touched:** ~/.polyrouter/runtime/package.json, ~/.polyrouter/runtime/node\_modules, hooks/postinstall.js, hooks/sqliteRuntime.js, hooks/trayRuntime.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Installation automatically runs a package hook., The hook creates a user runtime project and invokes npm to fetch SQLite dependencies., The hook also fetches a tray package and marks its binary executable on non-Windows systems. - **Evidence against:** No source inspected sends environment values, local files, or credentials to an unrelated endpoint., The runtime downloads are fixed dependency names and versions; no self-dependency chain was found., Autostart support is an explicit function, not called by the install hook. ## Affected versions and remediation This report applies to polyrouter@1.0.19. - Review the evidence and your use of polyrouter@1.0.19 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.
