Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. No concrete attack was identified in the inspected source. Credential handling is tied to requests matching the configured Expo API origin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-08T20:01:19.358Z - **Finished:** 2026-10-08T20:02:06.717Z - **Download time:** 508 ms - **Static scan time:** 7978 ms - **AI review time:** 38871 ms - **Total time:** 47359 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 concrete attack was identified in the inspected source. Credential handling is tied to requests matching the configured Expo API origin. - **Trigger:** Using CLI features that make authenticated Expo API requests. - **Impact:** No confirmed malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T20:02:06.717Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The request wrapper checks the destination origin before attaching a stored access token or session secret. - **Rationale:** Inspected source supports ordinary Expo CLI behavior and origin-restricted credential forwarding, with no install hook or concrete attack found. A clean verdict cannot be fully supported within the allowed citation coverage for all required finding paths, so this remains unresolved. - **Network endpoints:** https://staging-api.expo.dev, http://127.0.0.1:3000, https://api.expo.dev ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Low - **AI review observations:** The manifest exposes the package CLI and declares no install lifecycle hook., Stored Expo credentials are added to requests only after the request passes the Expo API origin check., The API origin is selected from Expo staging, local, and production endpoints., The inspected package paths show no independently confirmed attack behavior. ## Affected versions and remediation This report applies to @expo/cli@57.0.26. - Review the evidence and your use of @expo/cli@57.0.26 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.
