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 account changes flagged by the scanner are user initiated, but Firebase Analytics starts automatically after Firebase becomes ready and the package reports account events without an evident disclosure or opt-out. This is undisclosed runtime telemetry, so the package should receive a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-11-02T03:40:55.363Z - **Finished:** 2026-11-02T03:42:01.716Z - **Download time:** 520 ms - **Static scan time:** 1466 ms - **AI review time:** 64366 ms - **Total time:** 66353 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 Firebase Analytics activity and account event telemetry. - **Trigger:** After the integrator initializes Firebase and it becomes ready; account events are logged after signup or account deletion. - **Impact:** Allows runtime tracking of these account actions through the configured Firebase Analytics project. No credential theft or unrelated account action was identified. - **Evidence paths:** base/firebase/interface.js, base/webcomponents/form/signup.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T03:42:01.716Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The ready callback initializes Firebase Analytics when supported. The package then sends account creation and deletion event names through that instance; no telemetry opt-out is apparent in the inspected source. - **Rationale:** The account changes flagged by the scanner are user initiated, but Firebase Analytics starts automatically after Firebase becomes ready and the package reports account events without an evident disclosure or opt-out. This is undisclosed runtime telemetry, so the package should receive a warning rather than a publish block. - **Files touched:** base/firebase/interface.js, base/webcomponents/form/signup.js, base/webcomponents/settings/input/delete.js - **Network endpoints:** https://firebaseinstallations.googleapis.com/v1/projects/${t}/installations ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** When Firebase is ready, the package initializes Firebase Analytics whenever the SDK reports it is supported., The package logs \`create\_account\` and \`delete\_account\` events through that Analytics instance., The signup flow calls the account event logger after creating an account. - **Evidence against:** The events are sent through the Firebase application configured by the integrator; the source does not show credentials being sent to an unrelated host., Profile edits and account deletion are user initiated; deletion requires confirmation and reauthentication. ## Affected versions and remediation This report applies to pwa-auth@3.7.4. - Review the evidence and your use of pwa-auth@3.7.4 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.
