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. The flagged shell use checks the version of the BrowserStack CLI binary, and the outbound archive upload is directed to BrowserStack with a disable option. The manifest contains no install lifecycle hook, and the inspected source establishes no malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T07:42:14.077Z - **Finished:** 2026-10-17T07:43:21.575Z - **Download time:** 774 ms - **Static scan time:** 4707 ms - **AI review time:** 62016 ms - **Total time:** 67498 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. The package uploads runtime logs and redacted WebdriverIO configuration to BrowserStack for its service. - **Trigger:** The service reaches its log upload path during runtime cleanup when credentials are available and auto-capture has not been disabled. - **Impact:** Consumer project configuration is sent to the package-aligned BrowserStack service; no unrelated recipient or malicious command behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T07:43:21.575Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It archives logs and redacted configuration, then posts the archive with BrowserStack credentials to BrowserStack's observability endpoint. - **Rationale:** The flagged shell use checks the version of the BrowserStack CLI binary, and the outbound archive upload is directed to BrowserStack with a disable option. The manifest contains no install lifecycle hook, and the inspected source establishes no malicious behavior. - **Network endpoints:** https://upload-observability.browserstack.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle hook; its listed scripts are build, test, and prepack tasks., The log uploader can be disabled through a service option or environment variable., Config files are collected from the WebdriverIO config and passed through sensitive-content redaction before archiving., The uploader sends an archive with BrowserStack credentials to the BrowserStack observability endpoint., The cleanup helper runs the existing CLI binary only to obtain its version. - **Evidence against:** Runtime log upload includes captured configuration and package files, so it handles consumer project data; the inspected source directs it to BrowserStack and provides an effective disable option. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.39.0. - Review the evidence and your use of @wdio/browserstack-service@9.39.0 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.
