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 an install-time telemetry ping, but it is gated on existing explicit consent and sends only coarse metadata. Other sensitive operations are tied to named user commands, with no concrete malicious behavior found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-14T21:59:20.494Z - **Finished:** 2026-08-14T21:59:53.199Z - **Download time:** 502 ms - **Static scan time:** 1074 ms - **AI review time:** 31128 ms - **Total time:** 32705 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 install hook performs consent-gated anonymous telemetry; scanning and publishing network actions require explicit CLI commands. - **Trigger:** npm postinstall only after prior recorded telemetry consent; otherwise explicit extenshi commands. - **Impact:** May create an anonymous telemetry ID and send coarse install metadata after opt-in; no credential harvesting, remote code execution, or broad control-surface mutation found. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/cli.js, dist/telemetry-consent.js, dist/scan.js, dist/publish.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T21:59:53.199Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** consent-gated PostHog telemetry and user-invoked extension scanning/publishing - **Rationale:** Source inspection confirms an install-time telemetry ping, but it is gated on existing explicit consent and sends only coarse metadata. Other sensitive operations are tied to named user commands, with no concrete malicious behavior found. - **Files touched:** scripts/postinstall.cjs, ~/.extenshi/config.json - **Network endpoints:** https://eu.i.posthog.com, https://scan.extenshi.io, https://bff.extenshi.io, https://registry.npmjs.org/@extenshi/cli/latest ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** postinstall reads ~/.extenshi/config.json and can send an install telemetry event., The lifecycle script can create an anonymous ID in the same config file after consent. - **Evidence against:** postinstall exits unless recorded telemetry is exactly true., Install telemetry is limited to package/version, runtime, OS/arch, and anonymous ID., CLI telemetry prompts on an interactive first run before emitting events., Networked scanning and publishing are explicit CLI commands; scan upload is user-invoked. ## Affected versions and remediation This report applies to @extenshi/cli@0.14.2. - Review the evidence and your use of @extenshi/cli@0.14.2 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.
