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 install-time request is gated by a previously saved affirmative telemetry preference and reports limited package/runtime metadata. Reviewed runtime and dependency entrypoints did not establish a separate concrete attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-23T22:47:47.896Z - **Finished:** 2026-10-23T22:48:37.527Z - **Download time:** 1037 ms - **Static scan time:** 2188 ms - **AI review time:** 46406 ms - **Total time:** 49631 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 in the reviewed source. The install hook sends consent-gated telemetry containing package and coarse runtime details. - **Trigger:** Installation, only when an existing Extenshi configuration records telemetry as enabled. - **Impact:** The permitted request reports package version and coarse Node, operating system, and architecture details with an anonymous identifier. - **Review source:** ai\_review - **Reviewed:** 2026-10-23T22:48:37.527Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook reads the saved preference and posts an install event to the configured telemetry collector; CI and explicit opt-outs stop the request. - **Rationale:** The install-time request is gated by a previously saved affirmative telemetry preference and reports limited package/runtime metadata. Reviewed runtime and dependency entrypoints did not establish a separate concrete attack surface. - **Files touched:** ~/.extenshi/config.json - **Network endpoints:** https://eu.i.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs scripts/postinstall.cjs during installation, and the hook sends an install event only when ~/.extenshi/config.json already records telemetry: true; it skips CI and explicit opt-outs and sends package and coarse runtime metadata to the configured telemetry collector., The inspected CLI, smoke, login, source-archive, and rendering paths, plus the three prepared dependency entrypoints, show product functionality or library exports; no concrete attack behavior was identified in the reviewed source. - **Evidence against:** The postinstall hook makes an outbound request and permits an environment variable to override the collector host, but the request is gated on a previously recorded affirmative telemetry preference. ## Affected versions and remediation This report applies to @extenshi/cli@0.32.0. - Review the evidence and your use of @extenshi/cli@0.32.0 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.
