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. No malicious attack surface was confirmed. The user-invoked CLI optionally posts command telemetry and runtime context to Expo. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-08-06T22:08:11.498Z - **Finished:** 2026-08-06T22:09:04.639Z - **Download time:** 755 ms - **Static scan time:** 5366 ms - **AI review time:** 47019 ms - **Total time:** 53141 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 malicious attack surface was confirmed. The user-invoked CLI optionally posts command telemetry and runtime context to Expo. - **Trigger:** User runs the Expo CLI. - **Impact:** Command usage and environment metadata, including detected coding-agent context, may be sent to Expo telemetry. - **Evidence paths:** package.json, main.js, build/bin/cli, build/src/utils/telemetry/utils/agent.js, build/src/utils/telemetry/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T22:09:04.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opt-out telemetry for user-invoked CLI commands. - **Rationale:** Source inspection shows a normal user-invoked Expo CLI with no install-time execution. Its telemetry and coding-agent context collection are package-aligned, opt-out behavior rather than a concrete malicious chain. - **Files touched:** main.js, build/bin/cli, build/src/utils/telemetry/Telemetry.js, build/src/utils/telemetry/clients/FetchDetachedClient.js - **Network endpoints:** https://cdp.expo.dev/v1/batch ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Runtime telemetry includes detected coding-agent ID/session ID., Telemetry is enabled for CLI commands unless EXPO\_NO\_TELEMETRY is set. - **Evidence against:** package.json has no preinstall/install/postinstall hooks., main.js only starts the packaged CLI., CLI sends a basic command event to Expo telemetry., Agent detection is telemetry context only; no agent config writes found., Child processes invoke explicit developer tools (xcodebuild, ADB, Watchman)., No credential harvesting, remote payload execution, or persistence found. ## Affected versions and remediation This report applies to @expo/cli@57.0.13. - Review the evidence and your use of @expo/cli@57.0.13 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** internal/unstable-expo-updates-exports.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L2: // NOTE for Expo Maintainers: Do not add to this file. We want to remove this L3: module.exports = require('../build/src/expoUpdatesExports'); ``` ### 3. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. High: Sandbox Evasion Gated Capability - **Category:** Source - **Confidence:** 84.0% - **Path:** build/src/utils/errors.js - **Public source:** [View source]() Source gates dangerous network, credential, or execution behavior behind CI, host, platform, time, or geo fingerprint checks. Public source snippet (untrusted): ```javascript L41: } L42: function _child_process() { L43: const data = require("child_process"); ...

L112: // Only enable special logging when running on macOS and are running into the `EMFILE` error L113: if ('code' in error && error.code === 'EMFILE' && process.platform === 'darwin') { L114: try { ``` ### 7. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** build/src/start/platforms/android/adbReverse.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @expo/cli; repositoryIdentity = expo; dependency = debug L66: } L67: const debug = require('debug')('expo:start:platforms:android:adbReverse'); L68: let removeExitHook = null; ``` ### 8. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 9. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 11. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** build/src/start/server/metro/createTypescriptResolver.js - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```javascript stage = ast_semantic_analysis; reason = ast_trace_path_limit_exceeded; limitedFiles = 1 ``` ### 12. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** build/src/run/ios/XcodeBuild.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
