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. Inspected source supports ordinary BrowserStack service behavior, including a disclosed, configurable log and configuration upload to a BrowserStack endpoint. Scanner flags for process execution, networking, and dynamic loading did not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 81.0% - **Started:** 2026-10-21T12:36:45.978Z - **Finished:** 2026-10-21T12:43:13.024Z - **Download time:** 771 ms - **Static scan time:** 5091 ms - **AI review time:** 381183 ms - **Total time:** 387046 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 package behavior. The service uploads captured configuration and logs to a BrowserStack observability endpoint as part of its service operation. - **Trigger:** A WebdriverIO run reaches the service log-upload path; the upload can be disabled through the service option or environment setting. - **Impact:** The upload shares project configuration and logs with BrowserStack for service observability; no unrelated recipient or concrete malicious behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:43:13.024Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The service archives selected configuration and log files, redacts recognized sensitive values, and sends the archive using BrowserStack credentials to a BrowserStack endpoint. - **Rationale:** Inspected source supports ordinary BrowserStack service behavior, including a disclosed, configurable log and configuration upload to a BrowserStack endpoint. Scanner flags for process execution, networking, and dynamic loading did not establish a concrete attack. - **Files touched:** package.json, build/index.js, build/cleanup.js - **Network endpoints:** https://upload-observability.browserstack.com ### Review decision - **Verdict:** Clean - **Confidence:** 81.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no install lifecycle hook and exports the built service entry point., The service collects configuration and log files for upload to BrowserStack’s observability endpoint; its source provides a disable option., The cleanup entry point is separately exported; inspected source shows no concrete attack behavior., The gRPC files register DNS resolution and validate service configuration; cleanup sends a funnel event with Basic authentication to its configured instrumentation URL; the protobuf files define generated descriptors., The eight protobuf modules export descriptors for their respective google/protobuf schemas., The eight target modules provide protobuf text encoding, size-delimited serialization, well-known-type helpers, or generated google/protobuf descriptors., The eight modules define generated descriptors for their respective google/protobuf schemas., The eight target modules define protobuf message schemas, provide text-encoding and size-delimited wire helpers, and implement gRPC name-resolution load-balancer and subchannel-pool functions. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.41.0. - Review the evidence and your use of @wdio/browserstack-service@9.41.0 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.
