Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 15 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.17.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 found an automatic postinstall telemetry request, but it requires a previously recorded positive consent setting and sends limited installation metadata. The updater contacts the npm registry for this package's version; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T16:40:14.071Z - **Finished:** 2026-10-09T16:40:43.577Z - **Download time:** 1293 ms - **Static scan time:** 732 ms - **AI review time:** 27480 ms - **Total time:** 29506 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 was identified. The automatic postinstall sends limited telemetry only when a prior positive consent setting exists. - **Trigger:** Package installation triggers postinstall; sending additionally requires existing telemetry consent and no opt-out or CI guard. - **Impact:** A consenting installation reports package version and coarse runtime details; no confirmed attack effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T16:40:43.577Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script posts an anonymous install event to the configured telemetry host and exits on errors or timeout. - **Rationale:** Source inspection found an automatic postinstall telemetry request, but it requires a previously recorded positive consent setting and sends limited installation metadata. The updater contacts the npm registry for this package's version; no concrete attack behavior was established. - **Files touched:** package.json, scripts/postinstall.cjs, dist/cli.js, dist/auto-update.js - **Network endpoints:** https://eu.i.posthog.com, https://registry.npmjs.org/@extenshi/cli/latest ### 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 automatically after installation., The postinstall exits unless the existing config records telemetry consent as true., With consent, the install script sends an install event to a host configurable through EXTENSHI\_POSTHOG\_HOST; the payload includes an anonymous ID and basic package and runtime details., The CLI asks for telemetry consent before emitting command telemetry., The updater checks the npm registry for this package's latest version. - **Evidence against:** No evidence inspected shows credential collection, broad project mutation, or execution of a remote payload. The postinstall telemetry is consent-gated and fail-soft. ## Affected versions and remediation This report applies to @extenshi/cli@0.17.0. - Review the evidence and your use of @extenshi/cli@0.17.0 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.
