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, without a documented package-level opt-out. This is a runtime telemetry concern; the account-count events themselves are tied to explicit account actions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-01T21:55:22.673Z - **Finished:** 2026-11-01T21:56:26.938Z - **Download time:** 764 ms - **Static scan time:** 1494 ms - **AI review time:** 62007 ms - **Total time:** 64265 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:** Firebase Analytics is initialized automatically and may transmit runtime analytics without a documented package-level opt-out. - **Trigger:** The consumer initializes the Firebase app; on supported browser environments the interface initializes Firebase Analytics. - **Impact:** Undisclosed or unexpected runtime analytics collection is a privacy risk; the inspected package code shows no collection-disable control. - **Evidence paths:** base/firebase/interface.js, source/pwa-auth.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T21:56:26.938Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** getAnalytics(application) initializes the Firebase Analytics SDK, which loads Google’s gtag script. The package also logs account creation and deletion events during those user actions. - **Rationale:** The package automatically initializes Firebase Analytics after Firebase setup, without a documented package-level opt-out. This is a runtime telemetry concern; the account-count events themselves are tied to explicit account actions. - **Network endpoints:** www.googletagmanager.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After Firebase initialization, the interface automatically checks analytics support and calls getAnalytics(application); no collection opt-out is exposed in that path., The bundled Firebase Analytics SDK references https://www.googletagmanager.com/gtag/js., The README describes account-count events as occurring “if Analytics is on” but does not document that the package initializes Analytics automatically or provide a disable control., Analytics also records account creation and deletion counts; signup calls the creation event after account creation, and deletion requires confirmation and reauthentication. - **Evidence against:** The package has no install-time hook; prepublishOnly runs build steps., The account events concern the package’s stated authentication purpose and are triggered by account actions. ## Affected versions and remediation This report applies to pwa-auth@3.7.0. - Review the evidence and your use of pwa-auth@3.7.0 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.
