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. Source inspection confirms a postinstall telemetry ping, but it is skipped without previously saved positive consent and contains no credential or project-file harvesting. Other network, file, and process operations are aligned with explicit scanner, publishing, reporting, and login commands. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-21T10:08:55.059Z - **Finished:** 2026-08-21T10:10:26.274Z - **Download time:** 506 ms - **Static scan time:** 1103 ms - **AI review time:** 89604 ms - **Total time:** 91215 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 malicious attack surface. The lifecycle hook performs consent-gated anonymous telemetry only; network uploads of extension artifacts require an explicit scan command. - **Trigger:** npm install after prior telemetry consent, or explicit CLI scan/login commands - **Impact:** Writes Extenshi local configuration and sends limited telemetry only after recorded consent; explicit scans upload the selected artifact to the configured scan API. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/scan.js, dist/telemetry-consent.js, dist/login-runtime.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T10:10:26.274Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** consent-gated telemetry and user-invoked extension scanning - **Rationale:** Source inspection confirms a postinstall telemetry ping, but it is skipped without previously saved positive consent and contains no credential or project-file harvesting. Other network, file, and process operations are aligned with explicit scanner, publishing, reporting, and login commands. - **Files touched:** ~/.extenshi/config.json, scripts/postinstall.cjs, dist/scan.js - **Network endpoints:** https://eu.i.posthog.com, https://registry.npmjs.org/@extenshi/cli/latest, https://scan.extenshi.io, https://bff.extenshi.io ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** postinstall exists and can send an install event., Postinstall reads and may update ~/.extenshi/config.json. - **Evidence against:** Postinstall exits unless telemetry was previously recorded true., Install payload is limited to anonymous telemetry and coarse platform/version fields., Artifact upload occurs only through the explicit scan command., Browser launch and loopback listener are explicit login flow behavior., No hidden shell execution, remote code loading, credential exfiltration, or AI-agent config writes found. ## Affected versions and remediation This report applies to @extenshi/cli@0.15.2. - Review the evidence and your use of @extenshi/cli@0.15.2 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
