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 active postinstall automatically transmits persistent installation and, outside CI, configured Git identity data to a package-aligned endpoint unless an opt-out is set. This warrants a warning about default identity disclosure, but source inspection did not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-23T04:28:03.308Z - **Finished:** 2026-10-23T04:29:38.886Z - **Download time:** 1279 ms - **Static scan time:** 332 ms - **AI review time:** 93966 ms - **Total time:** 95578 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:** The postinstall hook sends installation telemetry to the package vendor, including a persistent installation ID and, outside CI, configured Git identity. This creates a privacy risk, though the source does not establish a hostile recipient or payload. - **Trigger:** Installing the package when its postinstall lifecycle runs and telemetry has not been disabled. - **Impact:** The vendor can associate installation events with a persistent ID and, outside CI, the configured Git display name and email. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/identity.cjs, install/git-context.cjs, install/policy.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-23T04:29:38.886Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector reads installation and Git identity data, builds a package-installed event, and posts it to the Hashbrown endpoint. - **Rationale:** The active postinstall automatically transmits persistent installation and, outside CI, configured Git identity data to a package-aligned endpoint unless an opt-out is set. This warrants a warning about default identity disclosure, but source inspection did not establish malicious behavior. - **Files touched:** package.json, install/postinstall.cjs, install/collector.cjs, install/identity.cjs, install/git-context.cjs, install/policy.cjs, ~/.hashbrown/installation-id - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall collector, and the hook checks that it is running as the package manager’s postinstall process., The collector builds an install event with package and machine metadata and sends it as an HTTP POST; it also includes a per-user installation ID., Outside CI, the event can include Git display name and email from configured Git identity., Collection has opt-out variables and sends by default to the Hashbrown install endpoint, with endpoint overrides restricted to loopback addresses. - **Evidence against:** The install event is package-aligned telemetry, and source provides opt-outs; the inspected code does not establish a hostile recipient or malicious payload behavior., The runtime entrypoints expose React components and hooks; the inspected dependencies implement JSON and Markdown parsing. ## Affected versions and remediation This report applies to @hashbrownai/react@0.8.0. - Review the evidence and your use of @hashbrownai/react@0.8.0 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.
