Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 3.7.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 package automatically initializes Firebase Analytics after Firebase setup and loads the Google tag script. The README mentions account-count events when Analytics is on, but does not explain the automatic initialization or offer a way to disable it, so this is a runtime telemetry concern. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-02T01:23:15.680Z - **Finished:** 2026-11-02T01:24:33.930Z - **Download time:** 260 ms - **Static scan time:** 1470 ms - **AI review time:** 76520 ms - **Total time:** 78250 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:** Undisclosed runtime analytics startup; no attack was identified beyond this telemetry concern. - **Trigger:** The application initializes Firebase and the browser passes Firebase Analytics support checks. - **Impact:** Analytics may collect runtime usage data associated with the application's Firebase project. - **Evidence paths:** base/firebase/interface.js, source/pwa-auth.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-02T01:24:33.930Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The library calls getAnalytics(application), which loads Google's gtag script. The package documents account-count events but does not describe this automatic startup or provide an opt-out. - **Rationale:** The package automatically initializes Firebase Analytics after Firebase setup and loads the Google tag script. The README mentions account-count events when Analytics is on, but does not explain the automatic initialization or offer a way to disable it, so this is a runtime telemetry concern. - **Files touched:** base/firebase/interface.js, source/pwa-auth.js - **Network endpoints:** www.googletagmanager.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After Firebase setup, an onReady callback automatically starts Analytics whenever the browser supports it., The bundled Analytics code loads a script from www.googletagmanager.com/gtag/js., The README mentions account-count events when Analytics is on, but does not describe the automatic startup shown in the runtime code. - **Evidence against:** The package is a Firebase authentication UI, and the README describes Firebase app setup as part of its use., Account creation and deletion events are logged after those account actions occur. ## Affected versions and remediation This report applies to pwa-auth@3.7.3. - Review the evidence and your use of pwa-auth@3.7.3 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.
