Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirmed automatic postinstall telemetry to the package's own service, with opt-outs and a loopback-only endpoint override. The collected Git fields are limited to name, email, and a known-host repository hint, and are omitted in CI; no concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-25T05:55:47.332Z - **Finished:** 2026-10-25T05:57:20.683Z - **Download time:** 772 ms - **Static scan time:** 336 ms - **AI review time:** 92242 ms - **Total time:** 93351 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:** No attack was identified. The postinstall hook sends installation telemetry to the package's service and can include configured Git identity outside CI. - **Trigger:** The package manager runs the package's postinstall script. - **Impact:** The inspected behavior is package-aligned installation telemetry; source does not establish a concrete attack surface. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T05:57:20.683Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook gathers an installation identifier, package and environment details, and limited Git identity, then sends a JSON event to the fixed package-aligned endpoint unless an opt-out is set. - **Rationale:** Source inspection confirmed automatic postinstall telemetry to the package's own service, with opt-outs and a loopback-only endpoint override. The collected Git fields are limited to name, email, and a known-host repository hint, and are omitted in CI; no concrete malicious behavior was established. - **Files touched:** install/postinstall.cjs, install/collector.cjs, install/identity.cjs, install/git-context.cjs, install/policy.cjs - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs the postinstall hook through install/postinstall.cjs., The hook is limited to the package manager's postinstall event and calls the collector., The collector reports package installation metadata to the package's hashbrown.dev endpoint; it omits Git identity in CI., The collector honors telemetry opt-outs, and endpoint overrides are restricted to loopback addresses., Git identity collection is limited to configured name, email, and a repository hint from the consuming checkout., The CommonJS and ESM entrypoints provide React signal subscription behavior; the prepared dependencies provide JSON and Markdown parsing code. ## Affected versions and remediation This report applies to @hashbrownai/react@0.8.1. - Review the evidence and your use of @hashbrownai/react@0.8.1 before allowing it.
