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. Source inspection confirms automatic install-time telemetry containing a persistent installation identifier and checkout context, gated by opt-out settings rather than affirmative consent. The vendor-aligned endpoint and package-install purpose reduce the risk; the behavior supports a warning, not a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-10-25T05:56:19.157Z - **Finished:** 2026-10-25T05:56:56.353Z - **Download time:** 514 ms - **Static scan time:** 127 ms - **AI review time:** 36555 ms - **Total time:** 37196 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 automatically reports installation and checkout metadata to Hashbrown telemetry. This is package-aligned telemetry, but the source relies on opt-out settings rather than affirmative consent. - **Trigger:** Installing the package with a package manager that runs postinstall, unless collection is disabled or its deadline expires. - **Impact:** Installation and checkout metadata can be disclosed to the telemetry service without an affirmative opt-in. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/identity.cjs, install/git-context.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-25T05:56:56.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook gathers a persistent installation identifier and Git checkout context, builds an installation event, and sends it by HTTP POST to the vendor endpoint. - **Rationale:** Source inspection confirms automatic install-time telemetry containing a persistent installation identifier and checkout context, gated by opt-out settings rather than affirmative consent. The vendor-aligned endpoint and package-install purpose reduce the risk; the behavior supports a warning, not a publish block. - **Files touched:** install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/identity.cjs, install/git-context.cjs, ~/.hashbrown/installation-id - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall collector during npm postinstall., The collector reads or creates a persistent per-user installation ID and discovers Git checkout context., It sends install events with package, platform, environment, consumer context, and sometimes Git identity to the configured endpoint., Collection proceeds unless an opt-out variable is set; endpoint overrides are limited to loopback, otherwise the vendor endpoint is used. - **Evidence against:** The destination is the Hashbrown vendor’s telemetry endpoint, and the event concerns package installation., The collector applies opt-out variables, CI restrictions on Git identity, bounded execution time, and a loopback-only endpoint override. ## Affected versions and remediation This report applies to @hashbrownai/ollama@0.8.1. - Review the evidence and your use of @hashbrownai/ollama@0.8.1 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.
