Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Running CLI commands can detect an AI coding-agent identifier and session identifier, then include them in telemetry sent off-device. This is unconsented collection of AI-agent session data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-08T14:13:23.982Z - **Finished:** 2026-09-08T14:14:59.385Z - **Download time:** 255 ms - **Static scan time:** 8028 ms - **AI review time:** 87119 ms - **Total time:** 95403 ms The recorded confidence comes from the underlying analysis.

This is unconsented collection of AI-agent session data. - **Trigger:** Run an Expo CLI command while telemetry is enabled and a supported coding agent is detected. - **Impact:** Exposes AI-agent and sandbox context to a remote telemetry service. - **Evidence paths:** build/src/utils/telemetry/utils/agent.js, build/src/utils/telemetry/Telemetry.js, build/src/utils/telemetry/clients/FetchClient.js, build/src/utils/telemetry/utils/constants.js, build/src/utils/telemetry/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T14:14:59.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detects coding-agent sessions and embeds their identifiers in posted telemetry. - **Attack narrative:** When a user runs the CLI, telemetry is active by default. The package calls an agent detector, collects the detected coding agent's identifier and session identifier, adds that data to every telemetry context, and posts the batch to cdp.expo.dev. It also records the sandbox provider. The collection is not needed to perform the requested CLI command and is sent automatically in a detached process. - **Rationale:** The package automatically exfiltrates detected AI coding-agent session metadata during normal CLI use. The lack of an install hook reduces installation risk but does not neutralize the runtime privacy attack. - **Files touched:** build/src/utils/telemetry/utils/agent.js, build/src/utils/telemetry/utils/sandbox.js, build/src/utils/telemetry/Telemetry.js, build/src/utils/telemetry/clients/FetchClient.js, build/src/utils/telemetry/clients/FetchDetachedClient.js - **Network endpoints:** https://cdp.expo.dev/v1/batch ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Runtime telemetry detects a coding agent and collects its identifier and session identifier., Every telemetry record embeds the detected agent data., Telemetry batches are posted to Expo's telemetry endpoint., Telemetry is enabled by default unless an environment opt-out is set. - **Evidence against:** The manifest has no install lifecycle hook., The normal executable dispatches named CLI commands; the collection occurs during CLI runtime, not installation., Credential headers are limited to requests whose origin is the Expo API. ## Affected versions and remediation This report applies to @expo/cli@57.0.23. - Avoid installing @expo/cli@57.0.23. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
