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. No confirmed attack surface was identified. The install hook performs package-local setup, and telemetry execution requires an explicit environment setting. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-29T03:25:48.797Z - **Finished:** 2026-09-29T03:28:28.984Z - **Download time:** 2061 ms - **Static scan time:** 543 ms - **AI review time:** 157583 ms - **Total time:** 160187 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 confirmed attack surface was identified. The install hook performs package-local setup, and telemetry execution requires an explicit environment setting. - **Trigger:** Package installation triggers the postinstall hook; the update helper requires direct execution. - **Impact:** No unconsented credential collection, foreign control-surface mutation, payload download, or destructive action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-09-29T03:28:28.984Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher imports its packaged runtime, while the helper invokes a local runtime in hint-only mode. - **Rationale:** The inspected lifecycle and launcher paths show package-local runtime setup and an explicitly gated telemetry path, not a concrete malicious action. No self-dependency or active exfiltration chain was found in the inspected entry points. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json registers only the inspected postinstall entry point., The launcher imports the packaged runtime after setting its argument vector., Runtime path helpers create only package-specific log and run directories., The update helper starts the local runtime with an upgrade hint-only argument., Install telemetry is gated on an explicit environment value before its child process is started. ## Affected versions and remediation This report applies to unbrowse@11.7.0. - Review the evidence and your use of unbrowse@11.7.0 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.
