Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** add-module.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L1: const path = require('node:path'); L2: const { pathToFileURL } = require('node:url'); ``` ### 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.

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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 57 - **Optional dependencies:** 0 - **Peer dependencies:** 3 - **Development dependencies:** 46 - **Published dependency-graph edges:** 60 ### Published dependency entries - @expo/code-signing-certificates ^0.0.6 (Dependency) - @expo/config ~57.0.1 (Dependency) - @expo/config-plugins ~57.0.1 (Dependency) - @expo/devcert ^1.2.1 (Dependency) - @expo/env ~2.4.0 (Dependency) - @expo/image-utils ^0.11.0 (Dependency) - @expo/inline-modules ^0.1.1 (Dependency) - @expo/json-file ^11.0.0 (Dependency) - @expo/log-box ^57.0.0 (Dependency) - @expo/metro ~56.0.0 (Dependency) - @expo/metro-config ~57.0.2 (Dependency) - @expo/metro-file-map ^57.0.0 (Dependency) - @expo/osascript ^2.7.0 (Dependency) - @expo/package-manager ^1.13.0 (Dependency) - @expo/plist ^0.8.0 (Dependency) - @expo/prebuild-config ^57.0.3 (Dependency) - @expo/require-utils ^57.0.0 (Dependency) - @expo/router-server ^57.0.1 (Dependency) - @expo/schema-utils ^57.0.0 (Dependency) - @expo/spawn-async ^1.8.0 (Dependency) - @expo/ws-tunnel ^2.0.0 (Dependency) - @expo/xcpretty ^4.4.4 (Dependency) - @react-native/dev-middleware 0.86.0 (Dependency) - accepts ^1.3.8 (Dependency) - arg ^5.0.2 (Dependency) - bplist-creator 0.1.0 (Dependency) - bplist-parser ^0.3.1 (Dependency) - chalk ^4.0.0 (Dependency) - ci-info ^3.3.0 (Dependency) - compression ^1.7.4 (Dependency) - connect ^3.7.0 (Dependency) - debug ^4.3.4 (Dependency) - dnssd-advertise ^1.1.4 (Dependency) - expo-server ^57.0.0 (Dependency) - fetch-nodeshim ^0.4.10 (Dependency) - getenv ^2.0.0 (Dependency) - glob ^13.0.0 (Dependency) - lan-network ^0.2.1 (Dependency) - multitars ^1.0.0 (Dependency) - node-forge ^1.3.3 (Dependency) - npm-package-arg ^11.0.0 (Dependency) - ora ^3.4.0 (Dependency) - picomatch ^4.0.4 (Dependency) - pretty-format ^29.7.0 (Dependency) - progress ^2.0.3 (Dependency) - prompts ^2.3.2 (Dependency) - resolve-from ^5.0.0 (Dependency) - semver ^7.6.0 (Dependency) - send ^0.19.0 (Dependency) - slugify ^1.3.4 (Dependency) - stacktrace-parser ^0.1.10 (Dependency) - structured-headers ^0.4.1 (Dependency) - terminal-link ^2.1.1 (Dependency) - toqr ^0.1.1 (Dependency) - wrap-ansi ^7.0.0 (Dependency) - ws ^8.12.1 (Dependency) - zod ^3.25.76 (Dependency) - expo \* (PeerDependency) - expo-router \* (PeerDependency) - react-native \* (PeerDependency) ## Package metadata - **Package:** @expo/cli - **Ecosystem:** npm - **Version:** 57.0.3 - **License:** MIT - **Version published:** 2026-06-30T21:08:11.413Z - **Package first seen:** 2026-06-30T22:54:56.538Z - **Package last seen:** 2026-10-08T20:02:29.661Z - **Known versions:** 13 - **Latest version:** 57.0.28 - **Appeal under review:** No - **Description:** The Expo CLI - **Author:** Expo - **Maintainers:** ide, brentvatne, expoadmin, exponent, bycedric, kudochien, alanhughes, tsapeta, expo-bot, philpl, wschurman - **Keywords:** expo, cli - **Artifact files:** 789 - **Artifact unpacked size:** 4,878,241 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
