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 confirmed malicious attack surface was established. Telemetry and platform commands occur during explicit CLI actions and are constrained to Expo services or local development tools. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-05T08:26:13.486Z - **Finished:** 2026-09-05T08:27:22.239Z - **Download time:** 765 ms - **Static scan time:** 8476 ms - **AI review time:** 59512 ms - **Total time:** 68753 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 confirmed malicious attack surface was established. Telemetry and platform commands occur during explicit CLI actions and are constrained to Expo services or local development tools. - **Trigger:** Running an Expo CLI command, including login, development server, or Android device setup. - **Impact:** No install-time execution, foreign control-surface mutation, or unconsented data exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-05T08:27:22.239Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked CLI telemetry, authentication, and local development tooling. - **Rationale:** The flagged primitives are bounded features of an Expo development CLI and are activated by user commands. The manifest has no registry install lifecycle hook, and inspection found no concrete malicious chain. - **Network endpoints:** api.expo.dev, staging-api.expo.dev, expo.dev ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package includes coding-agent and sandbox detection dependencies., Detected agent and sandbox identifiers are added to telemetry context during CLI use., The SSO flow starts a localhost callback server only after browser login is requested., A macOS error handler runs fixed Watchman recovery commands after an EMFILE error., ADB reverse commands operate only on authorized attached devices. - **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook., The manifest identifies a normal Expo CLI entry point., The inspected network authentication code uses Expo API endpoints and attaches credentials only for that API origin., No self-dependency, obfuscated payload, credential harvesting, or foreign agent-control write was found. ## Affected versions and remediation This report applies to @expo/cli@57.0.22. - Review the evidence and your use of @expo/cli@57.0.22 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. 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"); ... L107: * L108: * @see https://github.com/expo/expo/issues/29083 L109: * @see https://github.com/facebook/metro/issues/834 ... 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/api/user/expoSsoLauncher.js\#virtual:normalized:round1 - **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): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 8 ``` ### 12. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The package includes coding-agent and sandbox detection dependencies.
