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. This is default install-time telemetry to the package publisher’s own service, and it can include identifying Git name and email. The evidence supports a telemetry warning rather than credential theft or another malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-31T12:35:23.028Z - **Finished:** 2026-10-31T12:35:54.102Z - **Download time:** 519 ms - **Static scan time:** 341 ms - **AI review time:** 30213 ms - **Total time:** 31074 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:** Default install-time telemetry sends installation details and, outside CI, identifying Git configuration to Hashbrown’s service. - **Trigger:** Package installation runs the postinstall lifecycle hook unless telemetry is disabled. - **Impact:** Hashbrown receives installation telemetry that may identify the developer through Git name or email; this is an undisclosed-by-default install-time collection risk. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs, install/identity.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T12:35:54.102Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook gathers package and environment metadata, a persistent random installation ID, and optionally Git name, email and repository hints, then posts an event to the configured Hashbrown endpoint. - **Rationale:** This is default install-time telemetry to the package publisher’s own service, and it can include identifying Git name and email. The evidence supports a telemetry warning rather than credential theft or another malicious attack. - **Files touched:** ~/.hashbrown/installation-id - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs install/postinstall.cjs from its postinstall lifecycle script., The install collector sends a package.installed event with package, platform, runtime, package-manager and environment details to Hashbrown’s install endpoint., Outside CI, the event can include Git display name and email read from global or checkout configuration., The collector creates or reuses a persistent random installation ID, and supports telemetry opt-out environment variables. - **Evidence against:** The endpoint belongs to the Hashbrown project, and the collector does not follow redirects or read the response., The collected data shown is installation telemetry; the inspected code does not show credential collection or transmission., The telemetry can be disabled with DO\_NOT\_TRACK, npm\_config\_do\_not\_track, NPM\_CONFIG\_DO\_NOT\_TRACK or HASHBROWN\_TELEMETRY\_DISABLED. ## Affected versions and remediation This report applies to @hashbrownai/react@0.8.2. - Review the evidence and your use of @hashbrownai/react@0.8.2 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.
