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 excerpts. Full clean verification remains unresolved because required citation coverage exceeds the allowed citation count. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-08T20:01:39.814Z - **Finished:** 2026-10-08T20:02:29.661Z - **Download time:** 1006 ms - **Static scan time:** 4901 ms - **AI review time:** 43939 ms - **Total time:** 49847 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 excerpts. Full clean verification remains unresolved because required citation coverage exceeds the allowed citation count. - **Trigger:** The CLI is activated by running its command or making API requests through its fetch wrapper. - **Impact:** No confirmed unauthorized credential exposure or other attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T20:02:29.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected wrapper attaches stored credentials only when the request origin matches the configured Expo API origin. - **Rationale:** Inspected source shows origin-restricted credential forwarding and the expected CLI entrypoint. The required clean citation set exceeds the citation limit, so the review cannot establish a complete clean verdict; no independent source behavior supports a warning or block. ### Review decision - **Verdict:** Manual Review - **Confidence:** 79.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json routes the package entry and CLI command through main.js and build/bin/cli., The credential wrapper adds stored credentials only after checking the request against the configured Expo API origin., The URL check rejects non-string inputs and compares resolved request origin with the Expo API origin., The inspected files expose CLI and Expo development functions; their benign behavior does not establish full coverage of all required findings. ## Affected versions and remediation This report applies to @expo/cli@57.0.27. - Review the evidence and your use of @expo/cli@57.0.27 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.
