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. The credential handling examined is restricted to the configured Expo API origin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-08T20:01:15.633Z - **Finished:** 2026-10-08T20:01:46.911Z - **Download time:** 765 ms - **Static scan time:** 4825 ms - **AI review time:** 25687 ms - **Total time:** 31278 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. The credential handling examined is restricted to the configured Expo API origin. - **Trigger:** Running an Expo CLI command that makes an API request. - **Impact:** No credential exposure to an unrelated destination was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T20:01:46.911Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client checks the request origin before adding the stored token or session secret. - **Rationale:** The inspected manifest and runtime paths show no install hook or concrete attack behavior. A clean verdict requires citations for 15 distinct paths, exceeding the eight-citation limit, so the result remains manual review rather than a warning based on scanner similarity alone. ### Review decision - **Verdict:** Manual Review - **Confidence:** 72.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Low - **AI review observations:** package.json lists no preinstall, install, or postinstall hook., The API client adds stored credentials only when the request URL matches the configured Expo API origin., The CLI dispatches named commands to their corresponding Expo modules. - **Evidence against:** Static similarity alerts alone do not establish malicious behavior; inspected source showed no concrete attack. ## Affected versions and remediation This report applies to @expo/cli@57.0.25. - Review the evidence and your use of @expo/cli@57.0.25 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.
