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 performs package-aligned telemetry, but sends a persistent identifier and potentially personal Git identity without an affirmative opt-in. The endpoint and scope support a warning for privacy exposure, not a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-27T11:37:21.516Z - **Finished:** 2026-10-27T11:42:08.364Z - **Download time:** 1543 ms - **Static scan time:** 226 ms - **AI review time:** 285079 ms - **Total time:** 286848 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:** Automatic installation telemetry sends a persistent installation identifier and may send configured Git identity to the Hashbrown collector. This creates a privacy risk because collection does not require affirmative opt-in; no broader attack behavior was identified. - **Trigger:** Installing the package when telemetry opt-out variables are unset. - **Impact:** The collector may receive a persistent installation identifier and the user's configured Git display name and email. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/git-context.cjs, install/identity.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-27T11:42:08.364Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook collects installation details and sends them to the default Hashbrown endpoint; an endpoint override is accepted only for loopback hosts. - **Rationale:** The install hook performs package-aligned telemetry, but sends a persistent identifier and potentially personal Git identity without an affirmative opt-in. The endpoint and scope support a warning for privacy exposure, not a publish block. - **Files touched:** package.json, install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/git-context.cjs, install/identity.cjs - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs an automatic postinstall hook that starts install-event collection., The event can include package and system details plus available Git identity outside CI, and the collector sends it as a batch., Git identity collection includes the configured display name and email., The collector creates or reuses a persistent installation identifier in the user’s home directory., The default recipient is the Hashbrown installation collector; endpoint overrides are accepted only for loopback hosts., Telemetry opt-out variables are supported, but collection otherwise proceeds without an affirmative opt-in. - **Evidence against:** The collector is package-aligned telemetry sent to the Hashbrown endpoint, and the source shows no unrelated recipient or broader attack behavior., CI installations omit Git identity, and several opt-out variables disable collection. ## Affected versions and remediation This report applies to @hashbrownai/angular@0.8.3. - Review the evidence and your use of @hashbrownai/angular@0.8.3 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.
