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. Source inspection found no install lifecycle hook or concrete attack chain. The flagged subprocess and network behavior is consistent with the BrowserStack service’s CLI, Git orchestration, and flag-triggered reporting functions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-12T12:32:23.838Z - **Finished:** 2026-10-12T12:33:17.824Z - **Download time:** 1019 ms - **Static scan time:** 5191 ms - **AI review time:** 47776 ms - **Total time:** 53986 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 attack was identified in the inspected source. The flagged process execution supports BrowserStack service setup and test orchestration, while cleanup uploads are activated by explicit command-line flags. - **Trigger:** A consumer uses the service or invokes its cleanup entrypoint with upload-related command-line flags. - **Impact:** The inspected behavior supports service operation and requested reporting; no concrete attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T12:33:17.824Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The service starts its SDK CLI during setup and uses Git subprocesses to gather orchestration information. Cleanup sends supplied funnel data to the package’s instrumentation endpoint or uploads logs when requested by flags. - **Rationale:** Source inspection found no install lifecycle hook or concrete attack chain. The flagged subprocess and network behavior is consistent with the BrowserStack service’s CLI, Git orchestration, and flag-triggered reporting functions. - **Files touched:** package.json, build/index.js, build/cleanup.js - **Network endpoints:** APIUtils.FUNNEL\_INSTRUMENTATION\_URL ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the BrowserStack service and a separate cleanup entrypoint; its listed scripts contain no install lifecycle hook., Cleanup sends funnel data only when the corresponding command-line flag and data are present; its request goes to the package’s instrumentation endpoint., The spawned SDK CLI is obtained through the service’s setup path, and the other flagged process calls run fixed Git commands for test orchestration., No concrete malicious behavior was identified in the inspected runtime paths. - **Evidence against:** Importing the cleanup entrypoint starts cleanup handling, which can send supplied funnel data or upload logs when command-line flags request those actions., The service spawns a CLI process with the current environment, and test orchestration runs Git commands and reads their output. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.39.5. - Review the evidence and your use of @wdio/browserstack-service@9.39.5 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.
