Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 19 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.0.22 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The CLI sends runtime command telemetry by default, including detected agent and sandbox context, without documenting that automatic collection in its README. This is undisclosed runtime telemetry, so the package is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-29T19:35:11.175Z - **Finished:** 2026-10-29T19:36:13.455Z - **Download time:** 505 ms - **Static scan time:** 12039 ms - **AI review time:** 49735 ms - **Total time:** 62280 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:** Undisclosed automatic command telemetry. - **Trigger:** Running CLI commands, unless telemetry is disabled or Expo offline mode is active. - **Impact:** Expo receives command names, package and runtime details, and detected agent and sandbox context without this telemetry being disclosed in the package README. - **Evidence paths:** build/cli/index.js, build/telemetry/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-29T19:36:13.455Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI starts a detached worker that sends command and environment metadata to Expo’s telemetry endpoint. - **Rationale:** The CLI sends runtime command telemetry by default, including detected agent and sandbox context, without documenting that automatic collection in its README. This is undisclosed runtime telemetry, so the package is suspicious rather than malicious. - **Files touched:** build/cli/index.js, build/telemetry/index.js - **Network endpoints:** https://cdp.expo.dev/v1/batch ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Each CLI command starts a detached telemetry worker unless telemetry is disabled or Expo offline mode is active., The worker sends command telemetry to https://cdp.expo.dev/v1/batch and includes runtime, CI, agent, and sandbox context., The README documents metadata collection and opt-outs for the feedback command, but does not disclose the automatic command telemetry. - **Evidence against:** The automatic telemetry payload contains the command name and package version; the inspected code does not show command arguments or output being sent., Agent instruction-file updates are implemented as a CLI setup operation, rather than an install hook. ## Affected versions and remediation This report applies to @expo/agent-cli@1.0.22. - Review the evidence and your use of @expo/agent-cli@1.0.22 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.
