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. Static inspection found a consent-gated PostHog install ping, not a concrete malicious chain. Scanner signals are explained by package-aligned CLI functionality and source-analysis rules. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-16T12:47:21.563Z - **Finished:** 2026-08-16T12:48:10.091Z - **Download time:** 506 ms - **Static scan time:** 1085 ms - **AI review time:** 46936 ms - **Total time:** 48528 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; runtime network actions are aligned with explicit scanner and login commands. - **Trigger:** npm postinstall after prior telemetry consent, or explicit CLI commands - **Impact:** Sends bounded install telemetry only when prior consent exists; no credential harvesting, remote code execution, or agent-control mutation found. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/auto-update.js, dist/cli.js, dist/scan.js, dist/review-checks.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T12:48:10.091Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** consent-gated telemetry and user-invoked scan requests - **Rationale:** Static inspection found a consent-gated PostHog install ping, not a concrete malicious chain. Scanner signals are explained by package-aligned CLI functionality and source-analysis rules. - **Files touched:** scripts/postinstall.cjs, ~/.extenshi/config.json - **Network endpoints:** https://eu.i.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook can send an install telemetry event after reading shared Extenshi config. - **Evidence against:** Postinstall exits unless recorded telemetry consent is exactly true; it also skips CI, Do Not Track, and explicit telemetry opt-out., The hook sends a bounded PostHog payload and has a 2-second request timeout., Dynamic require only reads this package's package.json; review-checks contains detection rules, not runtime eval., Artifact upload and credential persistence occur through explicit CLI commands. ## Affected versions and remediation This report applies to @extenshi/cli@0.15.0. - Review the evidence and your use of @extenshi/cli@0.15.0 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.cjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.cjs ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** dist/review-checks.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern.
