Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 9.42.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically uploads exception data, stack traces, and function arguments to its own service when wrapped functions fail. This is not a clear attack, but the automatic runtime reporting can expose local or runtime details without an evident opt-out, so it warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-02T14:55:13.900Z - **Finished:** 2026-11-02T14:56:35.985Z - **Download time:** 255 ms - **Static scan time:** 5113 ms - **AI review time:** 76716 ms - **Total time:** 82085 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:** Automatic crash reporting may send runtime diagnostic details to BrowserStack. - **Trigger:** An error in a wrapped TestHub or Observability function. - **Impact:** Diagnostic data, potentially including local paths in stack traces or runtime argument details, leaves the environment. No credential theft or unrelated collector was identified. - **Evidence paths:** build/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T14:56:35.985Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler serializes function arguments and sends the exception, stack trace, hashed build ID, and filtered config in an authenticated POST. - **Rationale:** The package automatically uploads exception data, stack traces, and function arguments to its own service when wrapped functions fail. This is not a clear attack, but the automatic runtime reporting can expose local or runtime details without an evident opt-out, so it warrants a warning. - **Network endpoints:** https://collector-observability.browserstack.com/api/v1/analytics ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** On wrapped function errors, the code serializes the function arguments and calls the crash reporter., The crash report includes an exception and stack trace, then POSTs report data to BrowserStack’s analytics endpoint using Basic authentication., The reported config is PII-filtered, and the package metadata shows no install lifecycle hook. - **Evidence against:** The endpoint belongs to BrowserStack, the service this package integrates with., The report uses BrowserStack Observability credentials rather than discovered credentials from another service., The package’s shell execution checks the BrowserStack CLI binary version. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.42.2. - Review the evidence and your use of @wdio/browserstack-service@9.42.2 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.
