Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.8.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The automatic telemetry is an installation privacy consideration, but source inspection ties its default recipient to the package’s own Hashbrown domain and limits repository hints to the consumer checkout. The runtime entrypoints and inspected parser dependencies showed no separate attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-27T12:03:38.705Z - **Finished:** 2026-10-27T12:08:32.768Z - **Download time:** 1034 ms - **Static scan time:** 350 ms - **AI review time:** 292678 ms - **Total time:** 294063 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. Installation triggers package-aligned telemetry containing bounded installation and, outside CI, Git identity data. - **Trigger:** The package manager runs the postinstall hook during installation. - **Impact:** The telemetry discloses installation and potentially identifying Git metadata to the package-aligned service; inspected source does not establish malicious collection or an unrelated recipient. - **Review source:** ai\_review - **Reviewed:** 2026-10-27T12:08:32.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook collects an installation event and sends it to the Hashbrown telemetry endpoint; supported opt-outs disable collection. - **Rationale:** The automatic telemetry is an installation privacy consideration, but source inspection ties its default recipient to the package’s own Hashbrown domain and limits repository hints to the consumer checkout. The runtime entrypoints and inspected parser dependencies showed no separate attack behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook collects an installation event; the event may include Git identity outside CI, and the collector sends it to the default hashbrown.dev endpoint., The package identifies hashbrown.dev as its homepage and identifies its repository as the Hashbrown React package, supporting that the telemetry recipient is package-aligned., The runtime entrypoints expose React and Hashbrown functionality, while the two inspected dependencies are parser libraries; no separate attack behavior was identified in those paths. - **Evidence against:** Telemetry can be disabled through supported opt-out variables. Git identity is bounded, and repository hints are derived only from the consuming checkout’s local remote., The endpoint override accepts only loopback hosts; other values resolve to the package-aligned default endpoint. ## Affected versions and remediation This report applies to @hashbrownai/react@0.8.3. - Review the evidence and your use of @hashbrownai/react@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.
